Děvín

Děvín is a ruined castle crowning a 436-metre hill in the Ralsko Uplands, within the municipality of Hamr na Jezeře in the Česká Lípa district, Liberec Region. Together with the taller neighbouring peak Ostrý (Hamerský Špičák, 452 m) and nearby Schachtstein, it forms a trio of hills protected as the Děvín a Ostrý nature monument, lying a few kilometres southwest of the village of Břevniště.

How to get there?

The usual starting point is Hamr na Jezeře, a recreational village at the foot of both peaks, known for the Hamerský pond and the sandstone rock formations scattered around it. A red-marked hiking trail leads from Hamr na Jezeře toward the village of Chrastná and up to the ruins, running on foot through woodland that lies within the protected area. The whole region belongs to the Ralsko Uplands, an area once also used as the Ralsko military training ground.

What will you see?

The castle was founded in the 13th century to guard an old trade route running north toward Lusatia. In that period it belonged to King Přemysl Otakar II, and in 1283 King Wenceslaus II granted it to Jan of Michalovice. Built mainly in Gothic style with later Renaissance additions, the stronghold included perimeter fortifications, rectangular bastions, a four-sided tower at the eastern corner, and a horseshoe-shaped artillery bastion on its southern side.

From 1516 the castle passed to the Biberstein family, having previously belonged for a long stretch to the Vartenbergs — it was under their ownership, in 1444, that the stronghold withstood a siege by forces from Zittau and was never taken by force. Its downfall came only during the Thirty Years' War: in 1645 Swedish troops seriously damaged the castle, after which it was abandoned and gradually dismantled by local inhabitants, who reused its stone for building material.

Today visitors can see the remains of the perimeter walls, fragments of cellars, two castle wells, and traces of the former fortifications. Both courtyards have grown over with forest, and the surviving stretches of thick, roughly hewn sandstone walls give a sense of the strength of a stronghold that was never conquered. The site is listed as a Czech cultural monument and remains state-owned.

The Děvín a Ostrý nature monument

Covering nearly 34 hectares and protected since 1996 (re-declared in 2012 by the Liberec Region), the area includes beech forest, scree woodland, and pine stands, with heathland vegetation developing in the clearings between them. Numerous protected herbaceous plants grow here, and the fauna recorded includes seven species of bats, along with birds, amphibians, molluscs, and a rich variety of insects.

The history of the three hills is also tied to mining — iron ore was extracted here in the medieval period and again in the 17th and 18th centuries. Traces of that activity survive today as shafts, wells, and dug-out trenches that hikers can still come across while walking through the reserve.

When to visit?

Climbing the hill and exploring the ruins is best planned between spring and autumn, when the forest trail stays dry and easy to walk, and the views from around the castle and neighbouring Ostrý most reward the climb. It's worth combining the trip with a visit to Hamr na Jezeře itself and its pond, making for a full day of outdoor activity in the Ralsko Uplands.
