Elmstein Castle was built in the 12th century as a Palatine castle in order to guard the route through the valley. The feoffees held the title of Schenk, a German aristocratic title that originally meant cup bearer. The castle occupied by the Electorate of the Palatinate. Between 1220 and 1230, the lower curtain wall was built. Emperor Louis IV of Bavaria ceded the castle to his cousin, the Count Palatine. From 1419 to 1437, the castle was occupied by Count John V of Sponheim. In 1466, the castle was enfeoffed by Frederick I the Elector, to Erhard of Remchingen. In 1513, in the course of changes of ownership, Henry of Pagk was given the castle as a fief. During the German Peasants' War in 1525 the castle was damaged. Count Palatine John Casimir inherited the castle in 1576. The castle was also damaged during the Thirty Years' War in 1648. In 1689, during the War of the Palatine Succession, the castle fell into a permanent state of disrepair. Since then, the castle has been in private ownership.
The remains of the parts of the original curtain walls, the palas and the shield wall are still able to be seen today.
References:Střekov Castle (Schreckenstein) is perched atop a cliff above the River Elbe, near the city of Ústí nad Labem. It was built in 1316 for John of Luxembourg, the father of the Holy Roman Emperor Charles IV, to guard an important trade route to Germany. After changing hands several times, the castle was acquired by the Lobkowicz family in 1563. Its strategic importance led to occupations by Imperial Habsburg, Saxon, and Swedish forces during the Thirty Years' War, as well as successive sieges by Austrian and Prussian armies during the Seven Years' War.
Although Střekov Castle was heavily damaged during those conflicts and abandoned as a military installation by the end of the 18th century, the 1800s saw many poets and artists visiting the castle, drawn by a new trend of interest in romantic ruins.
