道加瓦河
Bolderāja is a neighbourhood of Riga, the capital of Latvia. It is located on the left bank of the Daugava River, in Kurzeme District. Bolderāja probably began as a fishing village. The area has been inhabited since at least the 10th century and possibly for a longer period, however there is no firm evidence because of variations in the course of the Daugava River and the shifting of sand dunes.
