In 1871 22 families founded the Villen-Sozietät Wilhelmshöhe, an association to develop a neighbourhood of villas on the eastern slope of the Kreuzberg. At the eastern slope, partially quite steep due to an exploited sand pit there, a little dead end was laid out named Wilhelmshöhe after Wilhelmshöhe Palace. Forty villas were planned, but only twenty were realised, since the area dropped in the favour of the better-off, when the urbanisation caused the adjacent quarters to be built up with blocks of flats. Four villas weathered the times, however, two of them overformed by later extensions alienating their original design. Lindenberg House, on Methfesselstraße 23-25 by Ewald Becher in 1874, is one of the villas in original design, however, dilapidated. It is - among others - the domicile of the house of literature, venue and organiser of readings named Lettrétage since 2006.
