Széchenyi Thermal Bath
The enormous neo-baroque bath complex in the City Park, opened in 1913 and fed from a deep thermal well rather than a surface spring. It is the postcard, all yellow facades and outdoor pools steaming in winter. The detail that surprises people: the outdoor pools, the ones in every photograph, are the newest and least interesting part of a much larger indoor complex most visitors never walk through.
Rudas Baths
An Ottoman bath still in use, its octagonal pool sitting under a domed roof pierced with coloured glass, built in the sixteenth century during Turkish rule. This is the oldest continuously functioning thing in the city's bath culture. Worth knowing before you go: parts of it still run single-sex on certain days, a direct inheritance from hammam practice rather than a modern policy.
Gellért Baths
The art nouveau bath attached to the Gellért Hotel on the Buda side, finished in 1918, all Zsolnay tilework and stained glass. It is the most architecturally deliberate of the major baths. The springs feeding it were in use long before the building existed, drawn on by both the Ottomans and, before them, the medieval Hungarians who ran a hospital on this spot.
Aquincum
The Roman provincial capital, now a ruin field and museum out in Óbuda, well north of anything a short visit usually covers. The Romans put their town here for the water. The name is thought to come from a Celtic root meaning abundant waters, Latinised, which means the thermal springs had already named this place before Rome arrived to formalise it.
Széchenyi Chain Bridge
The first permanent bridge between Buda and Pest, opened in 1849 after centuries in which the only crossings were boats and seasonal pontoons. It matters more than it looks: the two towns were physically joined by this bridge a full generation before they were legally joined in 1873. Engineering made the merger obvious before politics caught up.
Hungarian Parliament Building
The vast neo-Gothic riverfront parliament, completed in 1904 for a country that was then part of Austria-Hungary and had far grander ambitions than its constitutional position allowed. It was built deliberately oversized. The building faces the river and Buda, not the city behind it, so the intended audience was anyone arriving by water.
Buda Castle
The palace complex on the hill above the Danube, and much less medieval than it appears. It has been destroyed and rebuilt repeatedly, most recently after the siege of 1945, and the present exterior is a postwar reconstruction. The genuinely old material is underneath, in the medieval levels that the wartime demolition exposed.
Fisherman's Bastion
The white stone terrace of turrets above the Danube, and the thing most photographs of Budapest are taken from. It looks like a fortification and never was one. Built between 1895 and 1902 as a decorative viewing platform, its seven turrets stand for the seven Magyar tribes, and it has never defended anything from anyone.
Dohány Street Synagogue
The largest synagogue in Europe, finished in 1859 in a Moorish revival style, with a cemetery in its courtyard that exists because of the ghetto established here during the war. Synagogue courtyards are not normally burial grounds. That one is, and the reason is the single hardest fact on this page.
Shoes on the Danube Bank
Sixty pairs of iron shoes on the embankment, cast in 1940s styles, marking where Arrow Cross militia shot Jewish Hungarians into the river in 1944 and 1945. Victims were ordered to remove their shoes first because leather had resale value. It is deliberately at pavement level, with no plinth and no barrier.
