Windsor is the ruin of a windmill and later hunting castle. The original Dutch-style windmill built in 1843 of brick and local light clay slate. The windmill was used for milling until 1870, when the building changed owner and was converted into a summer-castle in New England style. The new owner, however, soon went bankrupt and since then an interesting building up to this time decay. To this day, maintaining only the damaged masonry. The building is located near Lovosice, close to the D8 motorway.
