Ludvík's Oak.

The torso of Ludvík's oak stands by the forest path connecting the hunting lodge in Střelná and the Dvojhradí hunting lodge in Mstišov. The oak was the third most powerful tree in northern Bohemia. It was named in honor of Ludwig van Beethoven's visit to the park in 1811. On February 28, 2012, the oak died in a fire. In May 2017, a resting place was built near the trunk of the tree and a new Ludvík oak tree was planted.
