History
Swedish fortress of Neumünde on the right bank, designed in a Dutch style by General Rothenburg in 1641, replaced the ruined Dünaburg Castle by 1680. In the second half of 16th century Daugava made a new river-bed and the new mouth about five kilometers to the west. Thence the Poles made the small fortress near the new river mouth. In 1582 the new fortress was inspected by King Stephen Bathory, who referred to it as Dynemunt. On August 1, 1608 the fortress was taken by the Swedes under Count Frederick Joachim von Mansfeld who renamed it Neumünde. This new fortress is located in the area of contemporary Daugavgrīva neighborhood of Riga. By 1653 a map issued by Swedish Military council showed that the Dünamünde fortress was destroyed and the Daugavgrīva castle was in ruins. Stones from the walls of castle were used for the construction of the new Daugavgrīvas fortress on the other bank of Daugava river. In 1700, Dünamünde was taken by the Saxons, but was retaken on December 11, 1701 by the Swedes again. Augustus II the Strong's campaign in Swedish Livonia had not produced satisfactory results. Though Dünamünde was captured and renamed "Augustusburg", he failed to take Riga or gain the support of the local nobility. Furthermore, Russia's forces had not yet entered the Great Northern War. Joachim Cronman later became commandant and died there on March 5, 1703. On August 10, 1710 fortress was taken by the Russians, when Commander :de:Carl Adam von Stackelberg|Carl Adam von Stackelberg surrendered to general field marshalBoris Sheremetev after being assured of free escort for his troops. In accordance with terms of the treaty of Nystad Daugavgrīvas fortress remained under Russian rule until Latvia's independence in 1918. Since 1850-1852 this location also used as Riga's winter port. The Russian government in 1893 changed the name of the Dynemunt on Russian : Усть-Двинск. The fortifications of the fort were completely rebuilt before the outbreak of the First World War. During World War I, the fort was bombed by German air forces. Soon the Germans took over the fortress, and in 1917, the German Emperor Wilhelm II personally inspected it. In 1940, the Soviet navy took over the fortress.
