Püspökvár, Episcopal castle in Győr, Hungary.

Püspökvár is the bishop's residence on the highest point of Káptalandomb in Győr, at the meeting of the Mosoni-Duna and the Rába. Its core is a four-story residential tower, square and robust up to two floors with a Baroque upper section. A Gothic chapel with an octagonal apse adjoins it to the south, and the gate opens into a barrel-vaulted hall with four Gothic niches on each side.

The core of Püspökvár is a residential tower built by Bishop Omodé after the Mongol invasion of 1241–42; its buried entrance once opened at the Danube bank. Fearing the Ottomans, the castle was ringed with bastions in the 16th century and rebuilt between 1561 and 1575 to plans by the Italian Pietro Ferrabosco. The Turks took it on 29 September 1594 and lost it on 28 March 1598, yet the bishops only returned to their seat in the mid-18th century.

The name means bishop's castle, reflecting the religious authority that once governed from here. Visitors can still see the chapel and rooms designed for spiritual duties and ceremonies.

The location sits where two rivers meet, making it easy to find. Wear sturdy shoes since visits involve going underground and climbing steep stairs within the tower.

A narrow staircase in the tower winds up to an old sentinel post positioned high in the structure. From that vantage point, past guards could watch both rivers and monitor vessels passing by.
