Plesse Tower, Wooden observation tower in Wanfried, Germany.

Plesse Tower is a 22-metre wooden observation tower on the 479.6-metre Plesse hill in the Wanfrieder Werrahöhen, about 2 km northeast of Wanfried. Its six-storey frame rests on a reinforced concrete foundation and was cut from 34 cubic metres of larch logged in the Wanfried forestry district. The viewing platform at 18 metres lies at 497.6 metres above sea level.

The structure was built in 1964 as a forestry project using carefully selected wooden materials from the local area. Its construction was part of the regional landscape development efforts in the post-war period.

The tower sits within a protected natural reserve where hikers and nature visitors pass through the landscape. It functions as a local landmark that people recognize and use as a reference point when exploring this area.

The tower reopened on 3 October 2023 after several years of renovation and is freely accessible again. The viewing platform sits at 18 metres, corresponding to 497.6 metres above sea level. Hikers reach it on the 9 km premium trail P5 Plesse, which starts at the Gatterbach waterfall in Wanfried's Elfengrund and passes the Plessefelsen.

The tower's four 21.5-metre corner posts were cut from four matching 40-metre larch trunks felled by the Wanfried forestry office; forester Dieter Schnell picked the trees himself. The side sections were assembled in autumn 1963 at the Wetzestein joinery and hauled up to the plateau on a Ruhlandt timber wagon.
