Northern Wavebreaker of Ainaži

According to historical records, in 1911, the Valmiera Society of Narrow-gauge Access Railways produced a project for connecting the northern end of the Ainaži wavebreaker to the coast. The purpose of the project was to install a branch railway line from the Ainaži station to the wavebreaker. The plan was to build a breakwater dam which would protect the anchorage against northern winds better than the natural headland. The construction of the dam started in 1912; it stretched for 361 m along the coast and jutted for 482 m out into the sea. A railway line was laid along the dam.

Building works were interrupted by World War I. In 1915, military authorities ordered the rails to be removed from the dam. The temporary jetty at the dam's end was also destroyed during the war, and the dam's wall was heavily damaged in two places by detonations. 78% of the above-water part of the structure was completely destroyed, and the remaining part – seriously damaged. Although in the wake of World War I, the Ainaži Port saw certain reconstruction works, the former animated activity gradually slowed down.
