Děvín, Castle ruin in Hlubočepy, Prague 5, Czech Republic.

Děvín is a castle ruin sitting on a hill near the Vltava River at the edge of Prague. The stone remains show foundations and some standing walls that look different depending on where you approach from.

Děvín was probably founded before 1338 by Štěpán z Tetína. Before 1376 it passed to the Carthusian monastery, and it most likely disappeared during the 14th century, though some hold that the monastery had it confiscated in 1420. In 1513 its remains served as a practice target for testing new artillery.

The name Děvín was later transferred to the hill and ruin from the Czech mythical hill of the same name; the castle itself was probably founded by Štěpán z Tetína before 1338. In 1513 its surviving walls served as a practice target for testing new artillery, a use recorded in written sources.

The ruin lies on Děvín hill at the northern edge of Hlubočepy in Prague 5; the site is reached on foot, as only terrain and vegetation traces of the castle remain. Paths climb the wooded hill from the Hlubočepy side, and the ground is uneven, so sturdy shoes help.

In 1513 the remains of Děvín served as a practice target for testing new artillery, so the ruin was shelled centuries after it had been abandoned. Visitors today see only terrain and vegetation traces of the two-part castle with its regular square ground plan.
