Located on Toome Hill, the Tartu Old Observatory is a landmark of Estonian science and the birthplace of local astronomy. Today, it is a museum where visitors can discover the history of astronomy, explore antique telescopes and interactive exhibits, and enjoy scenic views over Tartu. It is also home to one of the points of the Struve Geodetic Arc—a chain of survey triangulations extending from Norway to the Black Sea, through ten countries and over 2,820 km—which was added to UNESCO’s World Heritage List in 2005. Curious stargazers and history buffs alike can launch their visit by spotting the Tartu Old Observatory in the Museums section—no telescope required!
