Tauresium is an archaeological site in North Macedonia, best known as the birthplace of Byzantine Emperor Justinian I (ca. 482) and King Theodahad of the Ostrogoths (480).
Tauresium and the castle Baderiana were destroyed in an earthquake in 518 and the epicentre of the earthquake was in the nearby city of Skupi. As a gesture of gratitude to his birthplace, Justinian I rebuilt the city. According to the excavations that have been done so far, it is estimated that the oldest parts of Tauresium date from the 4th century and this oldest part is a castle with four towers known as Tetrapirgia.

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.
