Mokrice Castle, Medieval castle in Rajec, Slovenia

Mokrice Castle is a medieval castle on a hill in the northern part of the settlement of Rajec, in the Gorjanci Hills near the Croatian border. Its Gothic core was rebuilt in the 16th century into a fortified Renaissance castle by Ambroz Gregorijanec. In the castle courtyard, a cistern in the right corner was rediscovered and restored in 1809; a copy stands before the entrance, and a millstone lies to the left of the entrance.

Mokrice was first recorded in 1444 as a burg, but a Roman military fort called Romula had already stood on the same hill, guarding the road from Aquileia via Emona to Siscia; Romula appears on the 4th-century Tabula Peutingeriana. In the 5th century the site was rebuilt as a burg able to shelter up to 2,000 soldiers. In 1560 the Croatian landowner Ambroz Gregorijanec bought the castle, and his heirs rebuilt the Gothic building as a fortified Renaissance castle.

The Gregorijanec coat of arms shows a crow pierced through the neck by an arrow, with a six-pointed star and crescent above it. Legend says crows along the Sava sensed Ottoman horsemen first and flew toward the castle to warn of danger; one, hit by an arrow, still reached it. Ambroz Gregorijanec, who bought the estate in 1560, adopted the bird as his emblem.

The castle stands on a hill in the northern part of Rajec, in the Gorjanci Hills near the Croatian border, about 10 km from Bregana. The grounds hold an 18-hole golf course covering over 66 hectares, so allow time to move between the castle and the course. The Roman cistern lies in the right corner of the castle courtyard, with a copy in front of the entrance.

In 1988 the English pop duo Pet Shop Boys filmed the video for their single "Heart" at the castle, with actor Ian McKellen appearing in it. The same year a golf course was laid out in the castle grounds; it now has 18 holes and covers over 66 hectares.
