This residence (1904) was built for Swedish entrepreneur Swan Turnblad. With its raucous marriage of turrets, balconies, pillars and gables, the grey limestone structure resembles a fairy-tale castle. In 1929 the house became the headquarters of the American Swedish Institute. The interior has intricately carved wood panelling, as well as 11 rare porcelain-tile kakelugnar (stoves), and contains Scandinavian artefacts ranging from a 5C AD pre-Viking drinking vessel to contemporary glasswork.
