The Rakotzbrucke, also known as the Devil's Bridge, is a 19th-century bridge located in the Kromlau Park in Saxony, Germany. The bridge was built in 1860 made of basalt, a type of volcanic rock. It is famous for its unique, elliptical shape and the way it reflects in the water below, creating a perfect circle. 
 
The bridge was designed to be a perfect half-circle and when reflected in the water gives it a magical and otherworldly appearance. The bridge is supported by stone columns on both ends decorated as natural spires, adding to the bridge's mystical and surreal appearance.
