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. The area was made into a Polish customs post in 1606. The wooden houses built during the Polish era in 1603 may be the oldest in Riga. Bolderāja was the last district added to the city of Riga in 1924. Bolderāja was a district consisting mostly of private houses and low rise buildings, but after the 1970s five to nine floor blocks of flats were built by the Soviet government. The population of Bolderāja is largely Russian-speaking. From time immemorial the inhabitants of the area around the mouth of the Daugava river were renowned for being hard-working and courageous. River mouths were historically key strategic positions. Consequently, many battles were fought with numerous invaders.

Nicolai) was a Cistercian monastery in Daugavgrīva (German: Dünamünde) in Latvia, about 12 kilometres from Riga, of which Daugavgrīva has formed a district since 1959. The site was re-developed from 1305 as Daugavgrīva Castle.

The Capture of Daugavgriva by Swedish forces in July 1608 occurred during the Polish–Swedish War (1600–1611). Daugavgrīva castle (Polish: Dynemund, Swedish: Dünamünde) was the first objective of the Swedish forces during the campaign of 1608, due to its location near Riga (Daugavgrīva is Riga suburb today), and the fact that it could be used to block that city from the sea. When the Swedes, numbering 8000 troops and led by Joachim Frederick von Mansfeld, approached the fortress at Daugavgrīva, the Polish commander of the 130 strong garrison (with 40 cannons), Franciszek Białłozor, lacking in supplies and little hope of relief, decided to surrender. Swedes captured Daugavgriva on 5 August 1608.The Poles would not be able to recapture the fortress until more than a year later at the Battle of Daugavgriva (1609).
