Stagnov, Castle ruin in Rychtářov, Czech Republic

Stagnov is a ruined castle on a promontory above the Rakovec stream, 1.5 km west of Rychtářov. Its core was a roughly 30 × 25 m polygon enclosed by a mantle wall, with three ditches and a bailey on the south and a forecourt on the north. Only wall remnants and earthworks remain, now under forest.

Archaeological finds date Stagnov's founding to the late 13th century, when the Stange family settled the Drahany Highlands as fiefholders of Olomouc bishop Bruno of Schauenburg. It is first documented in 1381 as Nový hrad (New Castle), held by Peter of Šternberk after inheriting from his uncle Albrecht; Dědice castle nearby was then called Starý hrad. In 1397 it passed to Peter of Kravař, and by 1525 it was recorded as deserted.

The name Stagnov probably derives from the Stange family, ministeriales of Bishop Bruno of Schauenburg who settled Moravia in the 13th century. The castle was called Nový hrad (New Castle) to distinguish it from nearby Dědice, the "Old Castle"; the name Hrádek survived in the vanished town below the walls.

The ruin lies 1.5 km west of Rychtářov on a forested spur above the Rakovec, just before it joins the Malá Haná; the site is wooded and offers no view. Parts of the foundation walls were uncovered in 1924, and the terrain is uneven. The Březina military training area borders the site to the north.

The castle's name likely comes from the Stange family, ministeriales of Olomouc bishop Bruno von Schauenburg, who settled Moravia in the 13th century. The site was called Nový hrad (New Castle) to distinguish it from nearby Dědice, the Old Castle.
