The mentality and positive attitudes of the students, the academic staff and researchers to the Estonian national university had helped to preserve its atmosphere and restore Tartu University as the University of the Republic of Estonia. 1989-1992 were the years of structural changes, restoring the content of academic studies and old traditions. Tartu University can look back on its history of 370 years which is symbolised by the statue of Gustav II Adolf, re-erected on its original site, Royal Square, on St. George's Day in 1992 (created by Elisabeth Tebelius-Myren in 1991 from a plaster figure by Fogelberg) to defend the continuity of alma mater Tartuensis. In the main building of Tartu University (built in 1805-1809 in the classical style) there is the oldest museum in Tartu University - the Art Museum. In the History Museum of Tartu University housed in the ancient Dome Church on Toome Hill visitors can familiarise themselves with the history of the university. Johann Karl Simon Morgenstern opened the university library in the same building 200 years ago. The Botanical Gardens of the University, founded in 1803-1806, add charm to the ruins of the Tartu town wall and the bastion on the right bank of the River Emajõgi. The students' organisations preserve the ideas and traditions of the "student kingdom" of Tartu alive.
