Estate Whim is a restored 18th-century Danish sugar plantation now operating as an open-air museum, managed by the St. Croix Landmarks Society. The site includes the great house, the sugar mill tower, the wind mill, the cook house, and the enslaved workers' quarters — a complete plantation landscape that gives a far more complete picture of how this economy functioned than the great house alone would. The machinery in the sugar factory has been partially restored and you can walk through the crushing mill, the boiling house, and the curing house to trace the full process.
The museum is honest about the plantation system's violence and dependency on enslaved labor. The workers' quarters and the estate records are presented alongside the formal gardens and the grand house furniture. Whim is one of the best-preserved plantation sites in the US Virgin Islands, and possibly the most important single site for understanding St. Croix's history. It sits in the western half of the island, making it a natural stop when visiting Frederiksted.
