Cvilín Castle

Cvilín Castle (also known historically as Lobenštejn, Šelenburk, or Šelemburk) is a striking medieval ruin perched on Zadní Cvilínský hill, roughly 2 kilometers from Krnov and close to the Czech-Polish border. Standing 423 meters above sea level in the forest above the village of Úvalno, the site has long been a favorite destination for hikers exploring this corner of Czech Silesia.

How did the castle come to be?

The hilltop had prehistoric roots, having once held an early hillfort. The first wooden castle on the site rose in the first half of the 13th century under the Přemyslid dynasty, and control soon passed to the Benešovic family. The earliest written record of the fortress dates to 1238, when it appeared under the name Lobenštejn. That original wooden structure was destroyed in 1241 during a Tatar raid, but by 1250 the king had ordered it rebuilt in stone.

Who ruled over the castle?

By the end of the 13th century, the stronghold had come under the authority of the Duke of Opava. Its political weight grew further in 1440, when it became the seat of the Dukes of Krnov. In 1474 the castle was captured by the forces of the Hungarian king Matthias Corvinus. A turning point came in 1493, when the crown enfeoffed the estate, castle included, to Jan of Šelenberk and Kost. The new owner immediately launched a major reconstruction that continued until 1521, and it is from his family name that the fortress came to be called Šelenburk.

What did the fortress look like?

Cvilín is a Gothic-style stronghold, and its most distinctive feature is a massive cylindrical defensive tower — the largest of its kind anywhere in Czech Silesia. The castle was further protected by a deep moat cut directly into the rock, laid out in a shape close to a square. The fortress guarded the trade route running along the Opava River toward Krnov and onward into Silesia, making it a strategically important checkpoint in the region.

What happened to the castle afterward?

The castle was permanently abandoned after the Thirty Years' War, and the structure gradually fell into decay from that point on. Archaeological research carried out between 1817 and 1825 uncovered medieval pottery and remains of iron objects on the site. When the cellars were cleared, traces of a former mint that had once operated at the castle also came to light.

What can visitors see today?

The ruins today preserve wide defensive walls, a deep well, the round tower, and the surrounding moat. The site is protected as a cultural monument and remains freely accessible to visitors year-round.
