Tvrz Pasovary, Medieval fortified house in Světlík, Czech Republic.

Tvrz Pasovary is a ruined Gothic fortified house in the vanished village of Pasovary, part of Světlík in the Český Krumlov district. Its three-storey tower, entered by a portal over a drawbridge, survives with a projecting bay window (prevét), and the southeast corner holds a later palace. A moat once encircled the polygonal site.

The village of Pasovary was first mentioned in 1278, but the surviving Gothic fortified house was built in the second half of the 14th century. After 1437 it passed to Emperor Sigismund and then to the Višně family of Větřní, who held it until the Thirty Years' War. Confiscated in 1623, it was bought by the town of Český Krumlov, used only for farming, abandoned after a fire in 1907 and damaged by the Czechoslovak army after 1945.

The fortress has been a protected cultural monument of the Czech Republic since 1958. Today a local association from Pasovary looks after the ruins, and the site stands where the vanished village of Pasovary once lay.

The site is accessible by hiking from Světlík toward Slavkov, turning onto a field road to the right after roughly one kilometer. When exploring, move carefully as there are unsecured cellars beneath the ruins that require watchful navigation.

The tower retains a projecting bay window housing a latrine (prevét), a detail rare in Bohemian fortress ruins. The site also preserves the outline of a moat that once encircled the whole polygon-shaped bailey.
