Reinhardstein Castle is located in valley of the Warche, in the village of Ovifat in the municipality of Waimes (Weismes). It was built in 1354 for Wenceslaus of Luxembourg, while still Count, by his vassal Reinhard of Weismes.
In 1550 following the marriage of Anne Naussau to Guillaume of Metternich, Reinhardstein became the property of this important Rhineland family, until the French Revolution. Abandoned, it fell progressively into important ruin.
In the 19th century it was nearly destroyed by quarrying, and since 1969 has been reconstructed.

The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
