Kirkilai Observation Tower

 

KARST LAKELETS IN KIRKILAI

In the region full of sinkholes, this area is unique because of the highest density of sinkholes (more than 200 items per sq. km) and in particular circular lakelets. A circular lake indicates that the lake evolved from a collapsed sinkhole. When a sinkhole collapsed to expose the water table at the surface, the sinkhole was filled with water forming a small circular lake. A footpath runs across area making it possible to have a close look at these exceptional water bodies. This is one of two habitats in Europe where green sulphur bacteria (GSB) and purple sulphur bacteria (PSB) are present, the second one is in Italy.

In the territory of Biržai regional park, next to karst lakelets, a view tower is built; its form resembles a canoe or a sinking boat. The height of the tower is almost 32 metres. The width of the viewpoint, which is in 30 metres height, is almost 30 square metres. On the first floor there is a 27.75 sq. m. amphitheatre meant for gatherings, small events or just for relaxation.
