Szerencs Castle, Renaissance castle in Szerencs, Hungary.

Szerencs Castle is a fortification from the Renaissance period located in the Tokaj region with a distinctive three-storey gate tower and thick protective walls. The inner courtyard is surrounded by multiple chamber buildings and defensive structures that form an integrated defensive system.

A Benedictine abbey founded in the 13th century and first mentioned in 1247 stood here. In 1556 Ferenc Németi, a Transylvania supporter, seized it and turned it into a fortress with a palisade outer ward. Habsburg forces took it without a fight in 1565, and Rudolf II mortgaged it for 9,160 florins to Zsigmond Rákóczi, who rebuilt it in Renaissance style. Esterházy's troops sacked it in 1644; in the 18th century it was partly demolished and converted into a Baroque castle.

The castle now holds the Zemplén Museum, whose permanent exhibitions cover the history of postcards, Zsigmond Rákóczi and his era, the building history of Szerencs Castle, and the ex libris bookplates of Fery Antal. Part of the building also operates as a hotel.

The castle today functions as a youth hostel and cultural center, with various areas accessible to visitors for tours and exhibitions. It is helpful to check ahead about current events and opening times before planning a visit.

A 1635 inventory (urbárium) of the castle lists cannons on the outer bastions and, in the weapons house, 50 muskets and 11 smaller guns. The three towers of the inner castle were demolished in the second half of the 18th century, leaving only the southern tower standing.
