Tombia Castle was erected on the foundations of the crumbling east wing of the castle built on this site in the 13th and 14th centuries. The castle, with its late Baroque facade, was built between 1767 and 1773; Today the castle is home to the Estonian Parliament, and the national flag can be seen in three colours: blue, black and white flying over the 45.6-meter-high Hermann Hill as a symbol of Estonia's independence.
