Helfenburk Castle

Helfenburk is a castle ruin situated near the village of Úštěk in the Czech Republic, originally constructed by the medieval Bohemian nobility. The fortress dates back to the first half of the 14th century and was probably founded by Jan of Klinštejn, a member of the Lords of Klinštejn, a branch of the Ronovci family. Jan took his name from the castle, marking Helfenburk as a seat of his lineage.

In 1375, the castle entered ecclesiastical hands when Archbishop Jan Očko of Vlašim purchased it. He transformed Helfenburk into a countryside residence, overseeing a domain that incorporated neighboring fortifications such as Hřídelík castle. His successor, Archbishop Jan of Jenštejn, invested in enlarging the castle and used it to safeguard precious treasures, relics, and manuscripts from the nearby St. Vitus Cathedral during unstable times.

The turbulent period of the Hussite Wars and the following conflicts brought numerous changes in ownership. The castle was held at various times by figures including Aleš of Malíkovice, Půta III of Častolovice, the Berka brothers of Dubá, Jan Smiřický, and Zdeněk Konopišťský of Šternberk, an opponent of King George of Poděbrady. During this era, Helfenburk was besieged and seized by royal forces, after which King George granted it to the nobleman Petr Kaplíř of Sulevice.

Later, Wilhelm of Ilburg became the last aristocratic owner. He carried out renovations and favored Helfenburk over the nearby Ronov castle until his family line ended in 1538. Following this, the castle was inhabited solely by servants and gradually deteriorated. In 1622, during the violent aftermath of the Battle of White Mountain, imperial troops commanded by Marshal Buquoy plundered and set fire to Helfenburk. The Jesuit order from Liběšice subsequently acquired the surrounding lands, incorporating them into the estate of Úštěk.

In the late 19th century, industrialist Count Josef von Schroll purchased the ruins and undertook significant restoration work. He rebuilt the collapsed third floor of the main tower, turning it into a summer residence, and created a new side entrance, as the original medieval tower ingress had become inaccessible.

Since the 1960s, preservation and archaeological projects have been carried out by the Czech Union for Nature Conservation with the help of local volunteers. These efforts included excavating the castle’s well shaft, uncovering historical components such as a winch axle now exhibited near the site. Starting in 1978, a dedicated volunteer organization has maintained the ruins and provided guided access to the tower.

Historic records first mention Helfenburk in 1374 in a document detailing its sale to Archbishop Jan Očko. Earlier traditions relate that the Italian political figure Cola di Rienzo was imprisoned there around 1350. The final documented references to the castle as a noble residence date from 1591.
