Elektrenai is a city of about 14,000 inhabitants in Lithuania; since 2000 it is the capital of the Elektrėnai municipality. It is situated between the two largest cities in Lithuania – Vilnius and Kaunas. Elektrenai is one of the newest towns of Lithuania, having been established during the Soviet times as the living space for workers of the nearby power plant. Most of the buildings in Elektrenai are large monolith housing projects built during the Soviet times and there are no historical buildings. The town, however, is close to Elektrėnai Lagoon, an artificial lake that was created in order to cool down the Elektrėnai power plant. The water is several degrees warmer than water at the other nearby lakes.
