Drum
Castle was probably built by Alexander III in the late 1200's (1280).
Robert the Bruce gave it to William de Irwin in 1323 for his part
in the War of Independence. In 1619 an L-shaped wing was added to
the old keep. In 1876, the courtyard was restored and an arched entrance
added. Two years later, it underwent several modifications.
The family name was changed from Irwin to Irvine. The family were
Royalists during the troubled 18th century.
