Original home of Danish banker Hans Haagensen and his wife Sarah Julia Magens, it was built in 1827. Haagensen had been sent to St. Thomas from Copenhagen to help run the official Bank of St. Thomas. His wife was part of the St. Croix Magens family, related to the Magens that had their plantation on the now famous Magens Bay Beach. The couple raised their nine children in the house, which sits on the hillside directly above Hotel 1829. The house was built in the grand Charlotte Amalie town residence style, considered Greek revival because of the pediments above the doors and windows. There were no interior staircases to connect the two floors. The staircase with marble tiles is on the outside of the house. Haagensen House has five period exhibit rooms, managed by the St.Thomas Historical Trust. On display are West Indian antiques of the era, giving a sense of how well the merchant class of St. Thomas lived in the prosperous early 1800s.
