Riga, Latvia

Riga Castle (Latvian: Rīgas pils) is a castle on the banks of River Daugava in Riga, the capital of Latvia. The castle was founded in 1330. This structure was thoroughly rebuilt between 1497 and 1515. Upon the castle's seizure by the Swedes, they constructed spacious annexes in 1641. The fortress was continually augmented and reconstructed between the 17th and 19th centuries. Sometime in the 1930s, some renovation work was done by architect Eižens Laube. The Latvian government declared the castle its residence in 1938. Today it is the official residence of the President of Latvia as well as home to several museums.
