The Pesapuu watchtower is 30 meters high (the top observation platform is 27 meters from the ground) and it resembles a tree with two birdnests. Karmo Tõra, an architect, is the author of the idea.
The watchtower is eye-catching during both the day and the night. At night, lights of different colours are turned on to shed light on the so-called birdnests or observation platforms and the so-called golden egg on the top of the tower.
Tourists that reach the top are offered picturesque views of the Nightingale Valley and the rest of Võru County. Pesapuu is opened around-the-clock.
