Sárospatak Castle, Medieval fortress in Sárospatak, Hungary.

Sárospatak Castle is a medieval fortress set above a river valley with structures spanning multiple centuries of construction and expansion. The distinctive red tower from the 16th century rises prominently and provides views across the surrounding lowlands.

Péter Perényi built the castle and its fortified town walls between 1534 and 1542, after the earlier Pálóczi castle at the town's northern end fell into ruin following 1528. His son Gábor completed the palace wing in 1563. From 1616 the castle passed to the Rákóczi family as Zsuzsanna Lorántffy's dowry, and György I Rákóczi had it rebuilt as a residence.

The Rákóczi Museum occupies the palace rooms, which retain original Renaissance and Biedermeier furnishings and trace the history of the Rákóczi princely family. In the tower, the Rosen-Saal takes its name from the rose-shaped keystone of its vault; the leaders of the Magnate conspiracy are said to have met there in 1664. On the grounds of the outer fortification lies Hungary's largest wine cellar, with an exhibition on winemaking in the Tokaj region.

The castle stands above the Bodrog in the southeast of Sárospatak, not above a village. The Rákóczi Museum occupies the palace rooms, and Hungary's largest wine cellar, with an exhibition on Tokaj winemaking, lies in the outer fortification. The castle is separated from the castle garden by a moat.

The Red Tower's fourth floor holds the one-time "old palace", where fragments of 16th-century ornamental wall painting and carved Perényi coat-of-arms frames survive. The hall, originally timber-ceilinged, was vaulted in the 17th century. The top level, added in 1656 for cannon emplacements and covered by a tall pyramidal roof, kept three corner watch turrets; the fourth collapsed with the tower's south-east corner around 1702.
