Buda Castle, also known as Budai Vár and Budavári Palota, rises 70 m (230 ft) above the Danube on Castle Hill with layered courtyards, palace wings, and wide river panoramas. The mix of medieval traces, Habsburg-era rebuilding, and restored interiors makes the district feel like several centuries in one walk.
Start with a guided walking tour, then add a timed interior like St Stephen's Hall for deeper context and smoother entry, especially on weekends.
