Drummond Castle is known for its gardens, described by Historic Environment Scotland as the best example of formal terraced gardens in Scotland. The castle comprises a tower house built in the late 15th century, and a 17th-century mansion, both of which were rebuilt in Victorian times. The gardens date to the 1630s, although they too were restructured in the 19th century.
The lands of Drummond were the property of the Drummond family from the 14th century, and the original tower house was built over several years by John Drummond, 1st Lord Drummond of Cargill, from about 1490. In 1605 the 4th Lord Drummond was created Earl of Perth, and added to the castle.
The castle was sacked by the army of Oliver Cromwell in 1653, during the Wars of the Three Kingdoms. The 4th Earl of Perth was Lord Chancellor of Scotland under King James VII. He began the mansion house in 1689, before being imprisoned following the deposition of King James by William of Orange. He later fled to the exiled Jacobite court in France. The Drummonds continued to support the Jacobite cause in the Jacobite uprisings of 1715 and 1745. The family retained control of the estate until 1750 when the Drummond properties were declared forfeit and seized by the state. The estate was managed by the Commissioners for Forfeited Estates until 1784, when it was sold to Captain James Drummond (later created 1st Baron Perth). He began a number of improvements that were continued by his daughter Sarah and her husband, The 22nd Baron Willoughby de Eresby (1782–1865). These included the formal gardens and terraces in the 1830s. Queen Victoria visited the gardens in 1842.
The upper stories of the tower house were rebuilt and heightened in pseudo-medieval style in 1842–53. The mansion was renovated in 1878, to designs by George Turnbull Ewing. The castle is now the seat of The Rt Hon. The 28th Baroness Willoughby de Eresby, the daughter and heir of The 3rd Lord Ancaster.
The castle is set on part of a prominent spine of rock known as the Gask Ridge, a geographical feature that stretches several kilometres across Perthshire, but is particularly prominent and steep-sided at the site of the castle. The tower house, or keep, is no longer used as a dwelling. It is adjoined by a later, but better preserved, gatehouse (built 1629–30). Stretching between the tower house and the edge of the ridge, it was originally intended to control access to the courtyard behind, which has a fine view over the formal gardens. To the south of the castle on its rocky outcrop are the formal gardens.References:
Easter Aquhorthies stone circle, located near Inverurie, is one of the best-preserved examples of a recumbent stone circle, and one of the few that still have their full complement of stones. It consists of a ring of nine stones, eight of which are grey granite and one red jasper. Two more grey granite stones flank a recumbent of red granite flecked with crystals and lines of quartz. The circle is particularly notable for its builders' use of polychromy in the stones, with the reddish ones situated on the SSW side and the grey ones opposite.
The placename Aquhorthies derives from a Scottish Gaelic word meaning 'field of prayer', and may indicate a 'long continuity of sanctity' between the Stone or Bronze Age circle builders and their much later Gaelic successors millennia later. The circle's surroundings were landscaped in the late 19th century, and it sits within a small fenced and walled enclosure. A stone dyke, known as a roundel, was built around the circle some time between 1847 and 1866–7.
