Budapest is full of wonders waiting to be explored. While a lifetime would hardly be enough to uncover all its secrets, here are 10 must-see sights every visitor should experience.

To truly understand Budapest, one must walk its streets, cross its bridges, and discover its many layers of history and beauty. The city offers something new at every turn, from medieval fortresses and elegant boulevards to lively markets and green islands on the Danube. Although it takes a lifetime to get to know the Hungarian capital, here are ten places we recommend as an unforgettable introduction.

The Buda Castle District


The hill known as Várhegy has been a royal seat since King Béla IV had a stone castle built there after the Mongol invasion (mid-13th century); the complex evolved through Gothic and Renaissance phases under rulers such as Sigismund (15th century) and later took on the Baroque palace form most visible today when the Habsburgs rebuilt it in the mid-18th century. The modern silhouette, however, is a palimpsest: the Royal Palace you see contains 19th-century historicist additions by architects like Alajos Hauszmann and was heavily damaged in World War II before post-war reconstruction that finished in the 1960s; today the palace wings house the Hungarian National Gallery (Magyar Nemzeti Galéria) and the Budapest History Museum, while the district’s narrow streets shelter Matthias Church — a Gothic church with a multi-colored Zsolnay tiled roof largely restored by Frigyes Schulek in the late 19th century — and the neo-Romanesque Fisherman’s Bastion, built 1895–1902 as a decorative panoramic terrace. Don’t miss pausing at the bastion or the castle terraces for one of the best viewpoints over the Danube and the Pest skyline.

The Buda Castle District today is also a vast building site where long-lost palaces and façades are steadily returning. Under the National Hauszmann Program, whole sections of the Royal Palace and surrounding squares are being rebuilt as they looked before the destruction of the Second World War. On Dísz Square, the former Red Cross headquarters has been reconstructed in its ornate five-storey form, while the Archduke Joseph Palace, first designed in 1906, is rising again with its ceremonial staircases and richly decorated roofline. Along Szent György tér the northern wing of the palace is under reconstruction, and the redesign of the square itself is adding new gardens, terraces and more generous pedestrian zones. The Fehérvár Gate and its rondella bastion are also being reimagined to restore the medieval sense of a proper entrance to the hill. At the same time, ornamental features such as the dome lanterns and griffins of the former Defence Headquarters are reappearing, reinstating details long absent from the skyline.

The easiest ways up are the historic Castle Hill funicular from Clark Ádám Square, a brisk walk up the steps from the Chain Bridge, or bus routes that climb the hill. 


The Hungarian Parliament and Kossuth Lajos Square


Designed by Imre Steindl and constructed during the national building boom of the late Austro-Hungarian era, the Országház (Hungarian Parliament Building) was built between 1885 and the early 20th century and was completed in 1904;  its richly ornamented neo-Gothic façade and 96-metre dome were intended as a statement of Hungary’s modern, European identity. Inside the building’s central domed hall you can see the Holy Crown of St. Stephen, the medieval crown that symbolizes Hungarian statehood and which was moved into the Parliament’s Domed Hall in 2000 after long periods in other institutions and abroad; the Parliament Visitor Centre runs guided tours explaining the architecture, the legislative rooms and the story of the crown and regalia. The east side opens onto Kossuth Lajos Square, a civic space that hosts the Lapidarium and memorials connected to modern Hungarian history.

Just south of Parliament on the river bank, one of Budapest’s most moving memorials can be found: the Shoes on the Danube Bank. Created in 2005 by film director Can Togay and sculptor Gyula Pauer, the work consists of 60 pairs of cast-iron shoes, from men’s work boots to elegant women’s heels and tiny children’s footwear, lined along the embankment. It commemorates the thousands of Jews who were executed by the Arrow Cross militia in 1944–45; victims were ordered to remove their shoes before being shot into the river. The quiet simplicity of the memorial, with its haunting realism, makes it one of the city’s most powerful sites of remembrance, often adorned with candles and flowers left by visitors.

📌For an easy visit, take Metro line M2 or Tram 2 to Kossuth Lajos tér — the Visitor Centre and tour departures are right beside the square. 

Budapest Zoo & Botanical Garden


One of Europe’s oldest zoological parks, the Budapest Zoo and Botanical Garden opened on 9 August 1866 and became an immediate urban institution, combining scientific collections, landscaped grounds and ornate Art Nouveau animal houses. Early planners and designers such as Antal Szkalnitzky and Henrik Koch contributed to its 19th-century layout; later additions include monumental palm-houses and the Elephant House, and modern redevelopments have converted historic enclosures into more naturalistic habitats while preserving notable architectural elements. Located inside City Park (Városliget) beside the Széchenyi thermal baths, the zoo now houses thousands of animals across hundreds of species and remains a popular family destination.

📌The zoo is served directly by the Millennium Underground (M1) at Állatkert station and by local buses and trolleybus lines (e.g., trolleybus 72). 

The Chain Bridge (Széchenyi Lánchíd) and the view it frames


The Széchenyi Chain Bridge — designed by English engineer William Tierney Clark and built under the direction of Scottish engineer Adam Clark — was completed and opened on 20 November 1849 as the first permanent, modern bridge to link Buda and Pest; its 202-metre central span was a technical marvel of the time and its stone abutments are guarded by the famous stone lions carved shortly after the opening. The bridge is not only an engineering landmark but a visual stage: from its midpoint you get iconic, symmetrical views of Buda Castle, the skyline of Pest and the Parliament across the water, especially magical at dawn or when the façades are lit at night. After wartime destruction in January 1945 the bridge was rebuilt and reopened in 1949, preserving its 19th-century character.

📌Walk across from Deák Ferenc tér or from Clark Ádám Square (the lower end of the Castle Hill funicular) — it’s an easy, scenic stroll that links many of Budapest’s central sights.  The bridge has restricted car traffic with only buses and taxis being allowed to cross it.

Andrássy Avenue


Laid out from 1872 and formally inaugurated in the 1870s–1880s as part of Budapest’s Belle Époque expansion, Andrássy út is a tree-lined, 19th-century boulevard conceived to connect the inner city with Városliget; its façades host elegant Neo-Renaissance mansions, cultural institutions and city theatres and the avenue (with the Millennium Underground beneath it) is part of the UNESCO World Heritage ensemble. The Hungarian State Opera House, a Neo-Renaissance masterpiece by Miklós Ybl, was built between 1875 and 1884 and opened on 27 September 1884; its richly decorated foyer and auditorium still draw opera lovers and architecture fans alike. Not far away, at Andrássy út 60, the House of Terror Museum (Terror Háza) opened on 24 February 2002 in a building that served as the headquarters for oppressive regimes; the museum is a memorial and an exhibition space documenting the Arrow Cross and later communist secret police eras and is intentionally provocative in its presentation.

📌To explore the avenue and its landmarks, take Metro line M1 (the “Millennium Underground”) — stops like Opera and Oktogon put the main sites within a short walk. 

Városliget (City Park), Heroes’ Square and Vajdahunyad Castle


At the eastern terminus of Andrássy Avenue lies Hősök tere (Heroes’ Square), dominated by the Millennial Monument with its column and the sculptural colonnades that honor the nation’s leaders — a commemorative program started for the 1896 millennium celebrations and finished in the early 20th century. Behind the square, Városliget (City Park) opens into one of Budapest’s most-loved green spaces: here you’ll find Vajdahunyad Castle, a 19th-century romantic construction by Ignác Alpár first erected for the 1896 Millennial Exhibition (originally in temporary materials, later rebuilt in stone between 1904–1908) that cleverly reproduces elements of Romanesque, Gothic, Renaissance and Baroque Hungarian architecture; the castle now houses the Hungarian Museum of Agriculture (one of Europe’s largest agrarian museums). Around the park you’ll also encounter the Museum of Fine Arts and the Kunsthalle. Among the most striking recent additions is the House of Music Hungary, designed by Japanese architect Sou Fujimoto and opened in 2022. Its futuristic structure, with a roof perforated like a canopy of leaves, houses exhibitions, concerts, and interactive experiences that celebrate both Hungarian and world musical heritage. Just a short walk away stands the famous City Park Ice Rink, first opened in 1870 and one of the oldest outdoor ice rinks in Europe. In winter it transforms the lake beside Vajdahunyad Castle into a magical skating venue, while in summer the water is used for boating. On the other side of the park you’ll find the Széchenyi Thermal Bath, one of the largest spa complexes in Europe, built in 1913 in Neo-Baroque style. Its outdoor pools are open even in winter, with rising steam creating a unique atmosphere as bathers play chess in the warm water.

📌The simplest way to reach the square and park is Metro line M1 to Hősök tere station. 

St. Stephen’s Basilica

Named for Hungary’s first king, Saint Stephen (King István I, c. 975–1038), the basilica visible today is the result of a prolonged 19th-century project: construction began in 1851 under József Hild, continued under Miklós Ybl after Hild’s death (and after a dome collapse in 1858), and was finally completed by József Kauser with the church consecrated in 1905 (the basilica was granted the title of minor basilica and it is one of the tallest buildings in Budapest at about 96 metres). The interior houses the most venerated Hungarian relic, the “Holy Right” (Szent Jobb), traditionally the mummified right hand of King Stephen. The basilica’s panorama terrace in the dome gives expansive views over the city and it is a lively spot for concerts and seasonal markets.

📌A short, pleasant walk from Deák Ferenc tér brings you to the basilica’s steps. 

The Dohány Street (Great) Synagogue and Jewish Quarter


The Dohány Street Synagogue — often called the Great Synagogue — was built between 1854 and 1859 to designs by Viennese architect Ludwig Förster in an eclectic Moorish-Revival style; with seating for roughly 3,000 worshippers it remains the largest synagogue in Europe and one of the largest in the world. The complex includes the Hungarian Jewish Museum, the Heroes’ Temple, a memorial garden and the poignant Raoul Wallenberg Memorial and the “Weeping Willow” Holocaust Memorial marking the former Jewish ghetto; the site also connects to the broader, lively Jewish Quarter with its history, cafés and cultural revival.

📌The synagogue is on Dohány Street (District VII) and is easily reached from Astoria or nearby stops on Metro line M2. 


Váci utca, the Great Market Hall and Museum Boulevard  / Ráday Street area


Váci utca is Pest’s classic pedestrian shopping street, running from Vörösmarty Square down toward the Great Market Hall; while the street is tourist-oriented it gives a readable cross-section of 19th- and early-20th-century façades and cafés. At the southern end, the Central Market Hall (Nagyvásárcsarnok) — designed by Samu Pecz and opened in 1897 — is a neo-Gothic steel-framed market famous for its Zsolnay tiled roof and for local produce stalls selling paprika, salami, cheeses and Tokaji wines; the market’s ground floor offers fresh food while the mezzanine caters more to visitors with eateries and souvenirs. Nearby Museum Boulevard (Múzeum körút) hosts the Hungarian National Museum and several antique book stores, and the lively Ráday utca not far off is one of the city’s favorite restaurant and bistro streets for evening dining.

📌Váci utca and the market are easy to reach on foot from the Deák Ferenc/ Vörösmarty area or by tram to Fővám tér (Market Hall) and by metro lines M4. The closest metro station to the National Museum and Ráday utca is Kálvin tér where lines M3 and M4 intersect.


Margaret Island (Margit-sziget)


Margaret Island — the long, tree-lined island in the middle of the Danube named for Saint Margaret (Margit, 1242–1270), daughter of King Béla IV who lived in a Dominican convent there — has been a royal retreat, landscaped public park and health resort through the centuries. Today the island is cherished as a green refuge: its 13th-century monastic ruins, early 20th-century Art Nouveau water tower (1911), rose gardens, Japanese garden and the Musical Fountain all make it ideal for slow exploration; there are running tracks, a small open-air theatre, and Palatinus Strand (seasonal outdoor pools) on the southern tip.

📌Margaret Bridge gives direct pedestrian access from the city (and you can also get off trams 4 or 6 at the bridge and walk on), making it a five-to-ten minute escape from central Pest when you need calm, wide skies and a local sense of everyday Budapest life.
