Süntel-Tower, Observation tower in Bad Münder am Deister, Germany.

The Süntelturm is a 25 m round tower of Süntel sandstone masonry on the Hohe Egge, built from stone quarried in the nearby Pötzer quarries. Its walls are 1.45 m thick at the base and taper to 0.85 m, with an interior diameter of 2.40 m. A 95-step stone spiral staircase and a 12-step steel stair lead to the viewing platform, which also carries the amateur radio relay DB0SHG.

A wooden lookout, the Augusta-Turm, opened on the Hohe Egge in 1882; once it decayed, the present sandstone tower was begun, with its foundation stone laid on 24 September 1899 in the presence of the poet Hermann Löns. Built for 7,000 marks from Süntel sandstone quarried at nearby Pötzer, it was inaugurated on 17 May 1901. A sandstone annex with a small kitchen and guest room followed in 1910, and a telephone connection in 1912.

The tower's name comes from the Süntel ridge, and its sandstone came from the nearby Pötzer quarries. A sandstone annex added in 1910 held a small kitchen, a counter and a guest room, and the tower has had a hiking restaurant since then; the gastronomy was secured in 1988 when the district and the towns of Hameln, Bad Münder and Hessisch Oldendorf funded water, sewage and power connections.

The tower stands on the Hohe Egge at about 440 m, reached only on foot via the Turmweg and surrounding forestry and hiking paths; the nearest town centre, Bad Münder, lies roughly 6 km to the east-northeast. Inside, a stone spiral staircase of 95 steps plus a 12-step steel stair leads to the viewing platform. The hiking restaurant stayed open during the 2012 stair repairs.

The tower carries the amateur radio relay station DB0SHG on its top. On clear days the view reaches the Brocken in the Harz, about 94 km away as the crow flies. The sandstone came from the nearby Pötzer quarries.
