The Hadjigeorgakis Kornesios Mansion is situated near the Archbishopric, in the neighbourhood of Saint Antonios in Nicosia, Cyprus, where the wealthy notables of the Greek community traditionally used to live.

It opened on 3 May 1960 with the aid of public subscription, three years after a foundation was established to protect the property from developers who wanted to demolish the block.

The owner of the mansion, Hadjigeorgakis Kornesios, was a dragoman, the official interpreter for the Divan (Council) of the Sultan for thirty years from 1779.

The architectural plan of the building in the form of a Greek "Π" surrounds a central garden with a fountain and a private bathhouse (Hammam) which has three rooms.

Today the mansion, which was awarded the Europa Nostra prize for its exemplary renovation work, functions as the Ethnological Museum, Lefkosia (The House of Hadjigeorgakis Kornesios).
