The Semenec lookout tower was built in the 1930s on the site of the original wooden gazebo on a rocky lookout point above the river near Týn nad Vltavou. The two-storey reinforced concrete lookout tower offers a view of the Vltava valley and the town of Týn nad Vltavou. The view from here is best in spring and winter, when the valleys are not covered by tree leaves.
Road to the lookout tower leads along the red sign from the dock in Týn nad Vltavou, or you can leave the city center and join Alej Míru Street. It is lined with a tall linden alley, which was planted here in honor of Princess Stefanie of Belgium on the occasion of her marriage to Crown Prince Rudolf of Habsburg in 1881. Most of the trees are more than 100 years old.
