Svojkov Castle, Rock castle in Svojkov, Czech Republic.

Svojkov Castle is a rock castle cut into a 13-metre sandstone pillar standing on a 20-metre wooded hill. Rooms were carved on three levels, and a two-winged palace stood on the summit; today the remains of its masonry and a series of hewn rooms and passages survive.

First documented in 1355, the castle was held around 1370 by Ješek and in the early 15th century by Jan z Chlumu, a guide of Jan Hus to Constance. In 1444–1445 the robber knight Mikeš Pancíř ze Smojna seized it, and troops of the Lusatian cities captured and burned it. Abandoned around 1530, it was bought some 200 years later by Count Josef Jan Maxmilián Kinský and repaired in romantic style in 1780.

The castle gave its name to the Ctibor family, who began using the title "ze Svojkova" around 1437. In 1780 Count Josef Jan Maxmilián Kinský had the rock castle restored in Romantic style, adding a wooden staircase and later an excursion pavilion that has since vanished.

From the small car park by the Zámeček restaurant in Svojkov an improved path leads up to the ruin; the last 100 metres climb steeply along a forest trail. A red-marked route runs northeast from the same car park to the drinking water point in Modlivý důl.

The rooms of the rock castle were cut directly into a 13-metre sandstone pillar standing on a 20-metre wooded hill, forming three floors. In 1780 Count Josef Jan Maxmilián Kinský had the ruin restored in Romantic style, adding a wooden staircase and later an excursion pavilion that has since vanished.
