Photo: Daniel Vegel, Zoltan Tuba / CEU Budapest's architecture spans from ancient Roman ruins to award-winning contemporary buildings. Below is a subjective "best of" list, grouped chronologically. This map shows where each is located.

Heads up: Budapest has an excellent architecture center, Fuga, where plenty of books about Hungarian and regional architecture are available in English too.

Roman ruins

In the 1st century AD, the Roman Empire expanded to the Danube River, which served as its eastern border. Emperor Trajan made Aquincum, situated in the northern part of today's Budapest, the capital of Lower Pannonia province. In its heyday in the 2nd century, Aquincum was a city with 40,000 inhabitants. While Budapest's Roman ruins are smaller than ruins in some other places, there's no admission, they're easily reachable from downtown by public transport and usually empty, so you can have these two-thousand-year-old remains all for yourself.

1 - The two best preserved Roman ruins in Budapest

The Aquincum Military Amphitheater was a 13,000-capacity complex used for gladiator combats and chariot races. The Thermae Maiores ("Great Bath") was a sophisticated public bath system complete with a steam room and a gym inside a former fortress that housed the Roman soldiers. Bizarrely, a concrete overpass now runs above the ruins. You can visit Thermae Maiores for free from 10 a.m. to 4 p.m. (it's closed on Mondays); the amphitheater is accessible at all times. They're about a 15-minute walk from one another. If you're curious to see more Roman ruins, visit to the nearby Aquincum Museum too.


Medieval & Baroque

2 - The Castle Hill

The Castle Hill is split between the Buda Castle, and the civilian quarters packed with two- and three-story medieval residential homes. The countless battles waged on this small piece of land destroyed many of the original buildings, but the Baroque, and in some cases modern facades (e.g. the Hilton Budapest) stand on the original medieval walls. The narrow, winding streets of the area still exude a historic air.


3 - Király Baths (1565?)

Built by Ottoman ruler Sokollu Mehmed Pasha in the 16th century, this bath is one of the few remaining buildings from Budapest's century-and-a-half Ottoman occupation. The small openings on the dome admit little daylight, lending a mysterious atmosphere to the bathing hall. Of Budapest's thermal baths, this one is popular among local residents too.


Revival Architecture

In 1867, Budapest and Vienna became the joint capitals of the Austro-Hungarian Empire. The subsequent 50 years marked Budapest's golden era, when the city rapidly developed. Inspired by Paris and Rome, Budapest's revival architecture and its eye-catching grand boulevards from this time still dominate the city's layout.

4 - Andrássy Avenue & the Grand Blvd. (1876, 1896)

These two thoroughfares radically shaped Budapest's city fabric in the 19th century. The stately Andrássy Avenue is lined with imposing Renaissance Revival buildings. Often referred to as Budapest's Champs-Élysées, it connects the city center with the City Park. The Grand Boulevard is the main artery of modern Budapest, merging five different neighborhoods.


5 - Hungarian State Opera House (1884)

This is the finest work of Miklós Ybl, the most prominent Hungarian architect of the 19th century. The meticulously designed building features statues of Hungarian composers such as Ferenc Liszt, marble columns, and a giant bronze chandelier. It is considered to be one of the most stunning opera houses in the world.


6 - House of Parliament (1902)

Photo: Trover The House of Parliament is the largest building in Hungary. This turn-of-the-century Gothic Revival extravaganza of ornaments stretches imposingly along its Danube bank. The resemblance to the Westminster Palace was intended to enhance the building's legitimacy in the eyes of local residents. Parts of it are open to visitors, including the hall with the Holy Crown of Hungary and the former Upper Chamber.


7 - St. Stephen's Basilica (1906)

Towering over Budapest, the St. Stephen's Basilica is another statement-building conveying the city's imperial ambitions. The construction of the church took more than half a century and outlasted two of its chief architects. Behind the calm limestone exterior hides a dimly-lit central space, and the mummified right hand of St. Stephen, Hungary's first king. Note that the buildings's dome offers sweeping views of Budapest and is open to visitors.


Art Nouveau & Art Deco

Ödön Lechner created Hungary's unique style of Art Nouveau. Some call him the “Gaudi of Hungary” because his buildings loosely resemble those of the Spanish master. Lechner's signature style features fluid shapes, brightly-colored tilework, and ceramic motifs taken from folk art. A student of Lechner, Béla Lajta was another important architect: he shifted Lechner's national style toward art deco and modernism, which appeared in Budapest sooner than in most European cities.

8 - Museum of Applied Arts (1896)

With this building Lechner paid homage to Indian and Persian folk art. At the time, some ethnographers (falsely) believed that Hungary shared a common history with these Eastern civilizations, which is what inspired the building's ornamental details. For example, the floral patterns on the facade and the plain white entry hall are modeled after the Taj Mahal. The building is currently undergoing a major renovation and can't be visited.


9 - Postal Savings Bank (1901)

Photo: Lakáskultúra Lechner's art nouveau masterpiece nestles on a quiet downtown street by Liberty Square. He decorated the building's facade with beehives, symbolizing industry and hard work, and motifs taken from Hungarian folk art. The building's colorful green and yellow roof tiles are best taken in from afar, for example, the nearby corner of Bajcsy-Zsilinszky Road and Nagysándor József Street.


10 - Török Bank Building (1906)

Photo: budapestcity.org The steel-and-glass facade of this downtown art nouveau building is topped with an enormous mosaic. The colorful glass mosaic is a perfect foil to the clean simplicity of the rest of the building - they blend into a visually appealing unity. It depicts Saint Mary, Hungary's patron saint, surrounded by prominent Hungarian revolutionary figures.


11 - Parisiana (1909)

Photo: Kitervezte.hu With a grey, unornamented marble facade, Béla Lajta's Parisiana, originally built as a cabaret venue, shows early modernist and art deco characteristics (note that it was built in 1909!). There is a beautiful row of gilded cherubs perched atop the building, holding the stained glass lettering.


12 - István Széchenyi High School of Commerce (1912)

This large red-brick building emerges unexpectedly on the narrow Vas Street in the new-cool District 8. Its aluminum entry door and limestone frame depict themes of commercial transportation and Hungarian folk art. The latin inscription above the door means "It's not for school, but for life we learn."


Modernism

Following WWI, modernism left a distinct mark on Budapest's architecture. In fact, several well-known figures of the Bauhaus school were Hungarian (Marcel Breuer, László Moholy-Nagy), although many of them later migrated to the United States. In the 1930s and '40s, for people who used modern designs - mainly middle class, Jewish residents - it was a form of protest against the then still dominant Baroque Revival style, which they viewed as politically and socially outdated and backward-looking.

13 - Dunapark Apartment (1936)

Photo: 24.hu The highest concentration of modernist buildings are along Pozsonyi Road in Újlipótváros. The most spectacular is located at #38: the limestone clad facade hides a staircase complete with marble finishes, custom blue-rubber floors, and the interior meticulously designed down to the last detail. For the best experience, wait for a chance to get a sneak peek at the staircase.


14 - Napraforgó Street Housing Development (1931)

Modernism fans should be sure to visit the residential homes on Napraforgó Street in Buda. This row of 22 buildings was the result of an unusually progressive government decree in the 1930s that commissioned leading architects to build affordable housing in the modern style of the day. The result is a leefy street lined with charming single-family homes, each one a slightly different take on the same theme.


15 - Madách Houses (1938)

Madách Houses are a group of 11 clinker-brick buildings, separating the historic Jewish Quarter from downtown. The barely perceptible geometric patterns on the otherwise unadorned facade lend the buildings an understated grace. The sweeping arch was supposed to be the grand entry of a boulevard running all the way to the City Park, but its construction was halted during World War II and never continued.


Communist-Era

Socialist realism was the dogmatic, state-imposed artistic style in Hungary during the the first half of the 1950s. In architecture, it combined classical elements with communist ideology - imagine a carved relief on a building's columned entrance showing joyful laborers. These buildings looked painfully out-of-date at a time when sleek modern architecture reigned supreme in the Western world. By the end of the '50s, socialist realism ran its course and architects were allowed to return to modernist designs. But because of little money and limited access to high-quality building materials, many buildings from the '60s and especially the '70s don't stand the test of time.

16 - Former Communist Party HQ, District 2 (1952-53)

This former party building, one of the best examples of socialist realism in Budapest, tried hard to project the authority of communism. An unusually long and royal staircase is leading up to the building, which sits perched on the highest point of the park. In line with the socialist realist dogma, the facade is decorated with an oversized colonnade of Doric columns that feels bizarrely outdated for the 1950s. Before the fall of the regime, a five-pointed star topped the building.


17 - Körszálló - Hotel Budapest (1967)

Photo: indafoto.hu Contrary to popular opinion, Hungarian architects designed many tastefully modern buildings during communism, mainly up to the 1960s (state censorship of architecture wasn't as strict as in other fields like fine arts). One of the best examples of this is the 64 m (210 ft) tall circular hotel towering over the verdant Buda hills. Even if you aren't staying there, you can try asking the receptionists to let you up to the top floor, which offers sweeping views of Budapest.


18 - Prefab Residential High-Rises (1960-70s)

Tens of thousands of residential apartments made of precast concrete slabs were built in the 1960s and ‘70s to address Budapest’s critical housing shortage. These towering blocks were cheap and quick to construct, and also came with district heating and hot running water, amenities that were new to many residents. Today, however, these gray, lifeless boxes, which account for almost 30% of Budapest's apartment stock, are blights on their neighborhoods.


Post-modernism

Postmodernism emerged relatively late in Hungary - in the 1980s - because the communist leadership viewed it as a harmful aesthetic that originated in the "declining West." Its leading architect in Budapest was József Finta, whose buildings have fundamentally shaped Budapest’s contemporary skyline.

19 - "Makovecz House" (1993)

This four-story extension atop a 1867 Renaissance Revival building is one of the few Budapest works of legendary Hungarian architect, Imre Makovecz. Vertically repeating blank pediments are flanked by two curved towers dotted with Gothic-arched windows that are split by light blue columns. Enough said. Notwithstanding the spectacle (it's impossible not to stop and try to make sense of it), the building feels more self-serving than witty or sensitive to its surrounding.


20 - Police Headquarters (1997)

Photo: fintastudio.hu Finta's best work is the Police Headquarters building (colloquially the “Cops' Palace”). The beautifully proportioned, 58,000 sqm building looks like a high-tech battleship, or a sphynx fixing its vigilant gaze toward the city center. In addition to playful reflections, the building also includes subtle references to the work of Pritzker-winning architect, I. M. Pei.


21 - Lehet Market (2002)

Photo: blog.atlatszo.hu Love it or hate it, if you want to get a kick out of an intentionally kitsch Budapest building, you can't miss the Lehel Market. The boat-shaped glass-and-steel construction is packed with harsh colors and embellished, radically eclectic historical references like the bright-yellow oversized entablature. Aside from the quirky architecture, there's a lively market here that's popular among local residents, especially on Saturday mornings.


Contemporary

Large-scale contemporary buildings in Budapest are fewer in number than you might expect. Part of this has to do with the shortage of deep-pocketed developers. In addition, many downtown buildings are under landmark protections, so architects need to walk a fine line between preserving the old, be it the fabric of a street or the facade of a building, and creating something truly contemporary.

22 - Müpa Budapest (2005)

Photo: Müpa Budapest This enormous cultural building is Budapest's most important work of architecture so far in the 21st century. The exterior is clad in warm limestone, and oversized window panes that let in plenty of light and overlook the Danube and the city itself. Inside, note the gracious transition of materials: from wood to metal and glass and stone. Inside the building is the Ludwig Museum of Contemporary Art, and also the National Concert Hall, known for its incredible acoustics.


23 - Central European University Building (2016)

Photo: Daniel Vegel, Zoltan Tuba / CEU The main building of the prestigious Central European University, designed by O'Donnell + Tuomey, seamlessly blends old and new. The indented facade is distinctly modern, but it also fits into the otherwise 1820s street view. The inside, which is open for all to see, boasts expensive but understated details, unexpected color combinations, and contrasting materials.


24 - CET Building (2011)

The CET Building is a mixed-use cultural and commercial space consisting of a set of restored warehouses and a whale-shaped, high-tech structure inserted in-between. It's one of the few buildings with direct access to the Danube River and lined with several riverfront bars like Esetleg and Jonas Craft Beer House.


25 - M4 Subway Stations (2014)

Photo: ArchDaily The designs of Budapest's new metro line #4 are among the best works of contemporary Hungarian architecture. Playful lighting solutions, a crisscross system of concrete beams, and colorful mosaics paying homage to the buildings above ground are just some of the features. These disability-inclusive stations are wildly different from Budapest’s otherwise outdated subway stations (at the Kálvin Square station you can compare the two). The Fővám Square and Szent Gellért Square stations won the highly prestigious Architizer A+ Award in 2014.
