In the 1890s the aristocratic couple Walther von Hallwyl and his wife Wilhelmina ordered this mansion in the centre of Stockholm facing Berzelii Park.
The architect was Isak Gustaf Clason, responsible for many regal properties around the city like the Nordic Museum.
Hallywyl House is in a faithful Italian Renaissance style and while it might seem historic, the palace was advanced for its day and had phones, plumbing, central heating and electricity.
