The Old Observatory of the University of Tartu, in its time one of the most important astronomical centres in the world, is the pearl of Estonia's scientific history.
It was constructed between 1808 and 1810 to the designs of university architect Johann Wilhelm Krause on the site of a former medieval episcopal castle in the south-east corner of Toomemägi. Restoration work began in 2009; on 27 April 2011, it celebrated its 200th anniversary, and the observatory was reopened as a museum. There is plenty to discover here, whatever your age!

Since 2005, the Old Observatory, being a part of the Struve geodetic arc, belongs among the UNESCO world heritage sites.
