What is "blagard"

Blågård, also Blaagaard or Blågård Slot, was a royal country house near Peblinge Sø in what is now the Nørrebro district of Copenhagen, Denmark. Built in 1706 by Prince Charles of Denmark, in 1780 it was converted into a clothing factory before becoming a teacher training institution in 1791. After serving as a hospital in the early 19th century, in 1828 it became Nørrebro's first theatre until it was destroyed by fire in 1833.
