The first documented mention of Hammeries dates back to the 13th century. The Hammerrieser von Weimar family, whose civilian name was Spitzer, belonged to the rural nobility and had the right to bear arms.

This tower houses a marble entrance gate with an arch, above which the initials I. P. and A. P.
