Kirsten Bundgaard Swift was visiting her Danish family for Christmas 2014 after 30 years in the US, when she happened to hear about a local Renaissance castle for sale amidst the forests and beaches on Djursland, just 30 minutes north of Aarhus airport. She thought a visit would make for a fun excursion during the seasonal gluttony, but Bundgaard Swift had not reckoned on falling in love with the place. “We were shown around by a former nun, Sister Christiane,” she recalls, “and Sostrup had this sense of both adventure and tranquillity about it, which I thought many people could benefit from in their busy lives.” Sostrup was built by the noblewoman Sophie Bille between 1599 and 1606.
