Kostomlaty pod Milešovkou

A 14th-century castle ruin on a cone above the village of the same name, its corner tower reopened as a lookout in 2014 — the western gate of the Milešovka massif.

The castle above Kostomlaty was built in the first quarter of the 14th century on the site of an older Slavic stronghold, and for a moment it mattered greatly: in 1335 it was bought by the young margrave who would become Emperor Charles IV. The Hussite wars battered it, the 16th century abandoned it, and what stands today — solid stretches of wall, the outer parkán and the big corner tower — has been a cultural monument since 1964. The tower was restored and opened as a lookout in 2014, with the Milešovka group filling the eastern view. Maps often call the ruin “Sukoslav”, a name that comes from a 16th-century chronicler’s invention, not from history.

The village below has a shop and a pub, and the marked trails west of Milešovka pass through it — the climb to the castle takes about twenty minutes.
