Hegningarhúsið (Icelandic pronunciation:[ˈhɛkniŋkarˌhuːsɪθ], "The Penalty House") at Skólavörðustígur 9 in Reykjavík was a prison run by the Icelandic Prison Service. Built in 1872 by the designs of G. Ch. W. Klentz,[1][2][3] it was the oldest prison in Iceland.[4] All operations in Hegningarhúsið ceased on 1 June 2016.[5]
The origins of the Icelandic phrase "going to the stone" (fara í steininn) is purportedly due to the stone interiors of this prison.[6]
It was last used as a reception prison, where prisoners stayed for a short period of time when at the beginning of serving a sentence. The house was designated as historic property in 1978.[5]
There were 16 prison cells in Hegningarhúsið, small and narrow with poor ventilation. The cells were without toilets and sinks.
