The Tower of Unity (German: Turm der Einheit) is a 30-meter-high (98 ft) observation tower on Heldrastein, a rocky mountain belonging to Treffurt in Thuringia.
The tower of Unity has an unusual history and is also from unusual design, because it is additionally guyed by anchoring wires, although it is actually free standing.
At that time it was an open steel lattice tower additionally guyed with the radar facility on its top.
The area of this tower was not accessible for tourists at those days as it laid in the restricted area of the former border between West and East Germany.
In order to do this changes, which cost 205,000 DM, the radome on the top was removed and the tower body was covered with wood.
