Mon Bijou is estate 8 in St. Croix’s King’s Quarter. Based on appearances on historic maps, the windmill was likely built in the 1760s. Translated, the estate name means my jewel. The western half of the windmill tower collapsed.
The 1750 map indicates sugar cultivation but no animal mill. Both Beck printings depict and animal mill near the center of the estate. All the annotated Beck maps and manuscript copies combine estates 8 and 9, with sails added to the windmill on all these maps, except the 1770 annotated map that only added landowner names.
The 1799 Oxholm map depicts a windmill on a small hill in the northeast corner of mon bijou. The 1856 Parsons map depicts a windmill in the same relative location and several structures surrounded by what appears to be a wall to the north and a square to the west.
The 1921 topographic sheet specifies the ruins at Mon Bijou to be a chimney. Both the 1958 and 1982 topographic maps indicate ruins identifiable as a windmill at Mon Bijou.
All the annotated Beck maps and manuscript copies, from 1766 to 1791, attribute ownership to Peter Heyliger Junior for both estates 8 and 9.
McGuire geographic dictionary of the Virgin Islands (pp.128-129) notes mon bijou in French translates to my jewel.
