Biržai Regional Park Visitor Center houses the exposition intended to introduce the exceptional values of this protected area. The exposition is mainly focused on the topic “The region of the collapsing ground” because Biržai region is known for sinkholes, land subsidence, and interesting geological processes.
Biržai is a unique region with the land surface that goes through active formation by changing the landscape. The ground sinking occurs after gypsum deposits are washed out by groundwater followed by formation of misterious sinkholes: some sinkholes are dry (a famous object of natural heritage Cow‘s Cave), while others have turned into small lakes full of sulphur bacteria that are visible to the naked eye (the lakelets of Kirkilai).
The exposition in Biržai Regional Park Visitor Center, that is dedicated to this region, is very vivid and intriguing. A cold glass reception of the center is reminiscent of a sinkhole and therefore creates an impression as if you were yourself in a sinkhole. The exposition offers interactive stands-games “Process of sinkhole development”, “Ecosystem of the karst lakelets”. The stand that operates as a sandglass imitates a collapsing sinkhole, while other stands are used to show sinkholes before and after the collapse. All these things will help the visitors to understand the natural phenomena that are common in Biržai region.
The second exposition hall offers the exposition of minerals and rocks that introduces the geological riches of the region. The visitors will find here another interesting cognitive interactive cairn exposition stand. Thanks to this stand the visitors can experience the scale of the depth of the borehole and get to know the change of geological layers.
