There was originally a strong fortified castle Beritzholm few hundred meters from the present Bjärsjölagård Castle. It was built by Valdemar Atterdag in the 1300s and demolished in 1526. Peter Julius Coyet bought the estate from Crown in 1720. There was a lime factory in the beginning of the 19th century and two ovens still remain. The current main building was built in Rococo style in 1766 and the southern wing in 1812. The newer addition on the estate, was built in Romantic, German style in 1849-50, on a hill just south of the old castle. It is a three-story building flanked by two square towers. Today Bjärsjölagård is a hotel.

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.
