Tallinn University is the youngest of Estonia's 6 public universities. It was established on 18th March 2005 as a merger of Academic Library, Estonian Institute of Humanities, Institute of History, and Tallinn Pedagogical University.
The cache contains thematic items of the university and my home institute: Estonian Institute of Humanities.
"Lacrimae professorum" - meaning "professor's tears" - is one of the five official wines of the university -- normally white, but red in tempore examinum... In fact, I don't think the professors should cry here... other than out of a good laugh. Therefore I would ask you to include a "professor" joke when you log your visit on this webpage. (After you have found and logged the cache as usual.)
Here's a joke to get you started: Professor to noisy students: "Every time I open my mouth some fool speaks." Good luck, and have a laugh!
