This is a two-storey stone building with an upper storey made of half-timbering. In the basement there is a barrel vault with a perforated prison inside, which was reached from the outside through a hatch in the floor. The building has been on the list of monuments of the town of Bad Honnef since 27 November 1986.
The exact origin of the name "Hontes" is not known beyond doubt; an earlier name was "Hundt Hauß".
The first documented mention of the "Hontes" is from 1627 and the building has had various functions since then.
It served as a prison and, until 1800, as the custody of the Honnef court.
Until the beginning of the 19th century, it also served as Honnef's community centre.
It was then used as a secondary school, from 1934 under National Socialism as a home for the Jungvolk, and during the Second World War as a military detention centre.
In the following years, it served as a home for various local clubs, and was sold by the town to a local carnival club in 2014.
The Hontes can only be viewed from the outside
