Hungarian Parliament Building
Lipótváros (Kossuth tér) · $
4.8★100,000+ reviews
Imre Steindl's 1902 neo-Gothic colossus stretches 268 metres along the Danube and houses the Holy Crown of St. Stephen beneath its 96-metre dome. Interior tours run when the National Assembly is not sitting.
Insider tip: Buy timed tickets online days ahead, then see the building again at night from the Buda bank or a river cruise.
A 1902 neo-Romanesque fantasy of seven turrets — one for each Magyar tribe — built purely for the view across the Danube to Parliament. It is the most photographed terrace in Hungary.
Insider tip: The lower terraces are free and always open — come before 8am for empty arches at sunrise.
One of Europe's largest medicinal bath complexes, opened in 1913: outdoor pools steaming against neo-baroque yellow facades while old men play chess on floating boards. Saturday-night 'sparties' add DJs and lights.
Insider tip: Buy a skip-the-line ticket with a private cabin online and go early morning, when locals soak.
The much-rebuilt royal palace crowning Castle Hill holds the Hungarian National Gallery and the Budapest History Museum, ringed by ramparts with Danube panoramas. The 1870 funicular creaks up from the Chain Bridge.
Insider tip: Ride the funicular up, then walk down through the Várkert Bazár garden terraces to the riverbank.
Budapest's largest church, capped at exactly 96 metres to match the Parliament, and home to the mummified right hand of King St. Stephen. The dome deck gives a 360-degree sweep over Pest.
Insider tip: Take the lift (or 364 steps) to the dome an hour before sunset, and check the schedule of evening organ concerts.
Europe's largest synagogue (1859), a Moorish Revival landmark seating 3,000, with Imre Varga's steel weeping-willow Holocaust memorial in its courtyard. Theodor Herzl was born in the house next door.
Insider tip: Entry includes a guided tour — take it; closed Saturdays and Jewish holidays.

Three days is the sweet spot: one for Buda's Castle District, one for Pest's Parliament-to-Basilica core, and one for the Jewish Quarter plus a long soak at Széchenyi or Gellért. Add a fourth for Szentendre or the Danube Bend.
