The Stromburg was probably built in the 11th century and received its first documented mention in 1056 when Count Bertolf named himself after the Stromburg. In 1116, it was destroyed and subsequently rebuilt by Archbishop Adalbert I of Mainz. These early mentions likely refer to the 'old Stromburg' on the Pfarrköpfchen hill.
The first reliable mention of the Stromburg dates back to 1287. Under its protection, the village of Stromberg developed in the Guldenbach Valley, first mentioned in 1344.
During the Thirty Years' War, the castle was captured multiple times and was finally destroyed on March 3, 1689, during the War of the Palatine Succession. From the castle complex, the shield wall, the keep, a mighty gate tower, as well as parts of the outer wall and the outer ward, are still preserved. The Stromburg was the home of Hans Michael Elias von Obentraut, a cavalry leader of the Thirty Years' War.
From 1977 to 1981, parts of the castle ruins were restored and, with the addition of modern elements that now define its appearance, adapted for gastronomic use. Following another renovation that cost around eight million German Marks, since 1994, the building housed a gourmet restaurant led by Johann Lafer. It was initially named Le Val d’Or and was later renamed Johanns Küche in 2019. Since July 2022, the restaurant Das Kilger is managed there by Anthony Sarpong. In addition to the restaurant, the building houses a rustic tower room used as a secondary restaurant and the Stromburg Hotel.
The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
