The five-sided Renaissance castle at the centre of Sárvár is one of the most complete and best-preserved fortress-residences in western Hungary. The approach — across a long stone bridge that once spanned a moat, through a gatehouse — gives a genuine sense of the castle's defensive function. Construction began in the 16th century, and the Nádasdy family transformed it over the decades into an aristocratic residence without sacrificing its military character.
The interior now houses the Ferenc Nádasdy Museum, one of the finest castle museums in Hungary. Collections cover the region's history from Roman times through the Turkish wars, with a particularly strong display on the Hungarian Hussars — the famous light cavalry whose tactics influenced armies across Europe. The applied arts collection includes ceramics, textiles, weapons and furniture spanning four centuries. The ceremonial hall with its baroque ceiling paintings is the visual highlight.
