Alekšupīte River

The Alekšupīte River flows directly along the walls of many buildings which is why Kuldīga has been called the Venice of Latvia. Initially the buildings of the town centre were constructed as the suburb of Kuldīga. In 1701, during the Great Northern War, the Swedish army invaded Kuldīga Castle and in 1709 it became uninhabitable, but in the 19th century the castle ruins were relocated. Alekšupīte Waterfall – it was fixed and built up in the 17th century to use the stream to operate the first paper mill in Kurzeme. As the waterfall is created artificially and is located next to the unattended mill building. An annual race is held on the Alekšupīte, when the contestants run directly along the river bottom.

The historical centre of Kuldiga around the Aleksupite River
This is a unique small town in a certain sense, and it is the only one in the Baltic States which has remained in place since the 17th and 18th century. The town is around the small Alekšupīte River, and in some places the stream runs along the walls of the buildings. Because of this fact and the many bridges that are in town, Kuldīga has become known as “the Venice of Latvia.” Baznīcas, Liepājas, Kalna and other streets are full of interesting cultural monuments.
