Rinkesta Castle is a castle at Eskilstuna Municipality in Södermanland. Rinkesta was withdrawn from the crown in 1594 through a change to Privy Councillor (Kammarråd) Gustaf Gabrielsson Oxenstierna (1551-1597). The main building was repaired after a fire in 1698. The current appearance was given to the castle during an extensive repair in 1775, during the ownership of Swedish Supreme Court marshal (Överstemarskalk) Thure Leonard Klinckowström (1735-1821) who acquired the estate in 1768.
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.
