The original 13th-century tower of Drum Castle has been suggested as the work of medieval architect Richard Cementarius, who built the Bridge of Don in Old Aberdeen. It is believed to be one of the three oldest tower houses in Scotland. A large wing was added in 1619 by the 9th laird, and further alterations were made during the Victorian era. The castle and its grounds were granted to William de Irwyn in 1325 by Robert the Bruce, and remained in the possession of Clan Irvine until 1975. William de Irwyn was armour bearer/secretary to King Robert the Bruce. In June 1636 Sir Sir Alexander Irvine of Drum and his wife Magdalene Scrimgeour were censured for harbouring the outlaw Gilderoy. Drum played a role in the Covenanting Rebellion leading to its being attacked and sacked three times. In the 19th century it was the home of Alexander Forbes Irvine of Drum FRSE. He had inherited the estate in 1861, on the death of his father. In 1875/1876, he arranged for a restoration of the courtyard, and the addition of an arched entrance and angle tower. He was also partly responsible for a restoration of the chapel. There was an older church located here; it was modified to create the chapel in the 1500s and 1600s. In 1857, the west window was enlarged and the cross was added; a new roof was also installed and some restoration of the interior was completed. The site was once served by Drum railway station on the Deeside Railway. Service was discontinued in 1951.
Recent status
The castle has been a Category-A Listed property since 1987. The report states that the agreement with the National Trust was made in 1964 by Mr H.Q. Forbes Irvine, the 24th Laird, and that the agreement came into force in 1976, after 650 years of ownership by the Irvine Lairds. The summary states that the tower was built in 1280–1300, that the Jacobean Wing was added in 1619 and that modificants were made ca. 1800, 1840 and 1875. The Chapel is Category-B Listed as are the Walled Garden and East Lodge; in 1987, the garden was "derelict". The chapel, dining hall and estate may be hired for weddings and corporate functions. The current NTS web site however, discusses its Garden of Historic Roses, spread out over four distinct areas. The grand Victorian library with over 4,000 books was one of the attractions; the castle was also offering a "programme of temporary exhibitions throughout the year". A tourism web site added that the castle "contains superb furniture and paintings. In the 16th-century chapel are a beautiful stained glass window and the Augsburg silver Madonna". The site has a playground, a small shop and a tearoom. The castle is open to visitors during certain months of the year.
