Tuchoraz castel, Gothic castle ruin in Tuchoraz, Czech Republic.

Tuchoraz is a Gothic castle ruin featuring preserved stone walls and an intact entrance tower from the 15th century. The remaining structural elements still show the layout and form of its medieval military design.

Petr z Klučova built the first stone fortress above the Šembera before 1409; after 1468 Mikuláš z Landštejna had it rebuilt as a noble residence under Master Květoň, whose Czech inscription survives above the gate. Swedish troops besieged it in 1639 without success, but after 1770 it was almost entirely dismantled except for the entrance tower, its stone used to reinforce weirs and dams nearby.

The castle has been protected as a cultural monument since 1965. Above the gate survives a rare Czech inscription recording Master Květoň, who led the rebuilding after 1468. From 1542 the residence was permanently called a "zámek" (chateau).

Visiting requires advance contact with the owner to arrange entry and a tour of the ruins. Plan ahead since access is not freely open but can be organized with proper notice.

The entrance tower, about 20 metres high, keeps a rare Gothic vault: a straddling star vault on its second floor. An inscription above the gate names Master Květoň, who led the rebuilding after 1468 for Mikuláš of Landštejn.
