Elghammar is a house in Södermanland County, Sweden 80km southwest of Stockholm built at the end of the lake Lockvattnet.
The castle—or manor/Italian villa as the owner, the Duchess Christina d'Otrante (wife of Gustaf Douglas Armand Fouché d'Otrante, 7th Duc d'Otrante), preferred it to be perceived—is surrounded by forests and a farm.
