Biržai is one of the oldest towns in Lithuania. The town is located between two rivers called Apaščia and Agluona and two lakes named Širvėna and Kiluciai. This was the former town of the Dukes Radvilai and the town is proud of a bastion fortress palace which is an ornament to the town and a reflection of the past. The Earls Tiškevičiai left their footprints in the town in the middle of the nineteenth century. Biržai is decorated with St. John the Baptist Church and Evangelical Reformed Church. The town is a place where people do not tell even the angriest enemy a popular folk saying “Curl up and die” ("Kad tu prasemgtum!") as the saying may come true. When the groundwater washed the solute layers of gypsum, dolomite and limestone, the land collapsed making so called sinkholes which are over 9 thousand ones in the area. The people of Biržai have known for a long time how to exploit the mineral resources to treat diseases and how to cherish brewing traditions which came from ancient times. 

Biržai Regional Park Visitor Center (0 km). The relief structure of the Centre reception symbolizes the constitution of the sinkhole slopes. When the earth collapses, geological layers become naked which consist of a variety of rock. The ceilings of the Centre imitate sinkholes as well as. Interactive stands-games are installed in the exhibition called "The process of the development of the sinkholes”, “Sinkhole lakes’ ecosystem”, the stand as an hourglass imitating the sinkhole collapse, the other stands depict sinkholes before the crash, and after the collapse which will help visitors to understand about the ongoing natural phenomena in Biržai region.
