The park in front of the main building of Viljandi Manor is home to a 'world tree' bearing national patterns carved out of the old, dry oak. Both the tree and the large wooden Hiiu zither nearby made a home for themselves in the park in spring 2009, when Viljandi held the title of Forest Capital of Estonia. The park's 'orchestra' obtained new players in 2010: a willow whistle and bellows.
