Salaspils is a town in Latvia, the administrative centre of Salaspils Municipality. The town is situated on the northern bank of the Daugava river, 18 kilometers to the south-east of the city of Riga.

The Daugava or Western Dvina is a large river rising in the Valdai Hills of Russia that flows through Belarus and Latvia into the Gulf of Riga of the Baltic Sea. The Daugava rises close to the source of the Volga. It is 1,020 km (630 mi) in length, of which 352 km (219 mi) are in Latvia and 325 km (202 mi) in Russia. It is a westward-flowing river, tracing out a great south-bending curve as it passes through northern Belarus.
