Dole Island is the largest river island in Latvia, and it is the site of the Dole baronial estate. The mansion of the estate was built in 1898 by the aristocratic family which owned the estate. Today the mansion is home to the Dole Museum with a rich exhibition which tells about the lives of people on the shores of the Daugava River. The adjoining park features ethnographic buildings, as well as lamprey and salmon spawning grounds. There are five unique cannons that were found in Salaspils when a new stadium was being built there. In 1910, a tsarist military camp was here, and a monument to Tsar Peter the Great was unveiled. One of the cannons is in the exhibition of the museum itself.

The bridge was built in 1906. Part of it was blown up during World War I and later restored. During the Soviet occupation, one needed special permits to cross the bridge. Military ships and other vessels used the canal, because one of the largest military bases in the USSR was sited here. In the summer of 2006, one month before the bridge’s centenary, a Georgian-flagged tanker, the Anna, rammed into the northern support structure of the bridge, and that destroyed the bridge’s turning part beyond recognition. The bridge was renovated and reopened in 2009. You can look at the bridge and cross it at any time.This is a unique engineering monument, and it is the only drawbridge of its kind in the Baltic States. It takes just five minutes to turn the two parts of the bridge.
