Constitution Hill is estate 25 in St. Croix’s Queen’s Quarter. Based on appearances on historic maps, the windmill was likely built in the 1750s. The windmill was blocked to store water after decommissioning. The inscription on the main entrance keystone says LM S ANoC 1778. Since the windmill appears on earlier map, this likely does not indicate a construction date. The windmill tower is in good condition.
The 1750 map indicates sugar cultivation with structures including an animal mill in estate 25. The first Beck printing had an animal mill and the second changed it to a windmill. The windmill appears on the annotated Beck maps and manuscript copies through the 1770s. With these dates for a windmill existing here, the inscription on the main entrance keystone likely does not represent a construction date: LMS ANoC. 1778.
The 1799 Oxholm map shows a windmill as does the 1856 Parsons map. All the 20th-century topographic maps show ruins identifiable as a windmill at Concordia.
The 1750 map attributes ownership to James Hughes. Hughes must have died by 1766, since his widow appears as owner on the 1760s maps, with the 1770 maps attributing ownership to Friis Eilschow. By 1790 ownership transitioned to General Schimelman.
McGuire geographic dictionary of the Virgin Islands (p.58) provides location information and early ownership information for the Widow Hughes.
