Cullerlie stone circle, also known as the Standing Stones of Echt, consists of eight irregular stones of red granite arranged at approximately equal intervals to form a circle of 10.2 m diameter, enclosing the same number of small cairns.
At the time that the circle was built in the second millennium BC, the surrounding landscape was characterised by wet bogs, and the stones were transported to the site from higher ground some distance away. The tallest of the stones marks the north side of the circle. A 2004 survey of the site discovered that several of the stones had been carved with previously unnoticed cup marks.
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.
