The church of St. George was part of the Bernardine Monastery. The first wooden church was built in 1468. It was replaced by the current brick church in the late 15th century and completed before 1503. It’s been ruined by fire three times, suffered the wrath of the Moscow army during the war of 1656-1659 and then had a bit of a rest during the 18th century before Napoleon turned it into a warehouse.
During Soviet times, the church was used to store medicine. It was returned to the Friars in 1993 in a pretty shabby condition, and restoration of its outstanding if run-down Gothic, Renaissance and Baroque interior has been slow to say the least. Ongoing restoration work has seen the addition of a new roof although the church itself remains locked for the foreseeable future.
References:The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
