Merchiston Tower: Historic Seat of Clan Napier and Birthplace of Logarithms

Origins and Historical Significance of Merchiston Tower

Merchiston Tower, also known as Merchiston Castle, was likely constructed around 1454 by Alexander Napier, the 2nd Laird of Merchiston. It served as the ancestral seat for Clan Napier and remained in their possession for centuries. The tower is historically significant as the birthplace of John Napier, the 8th Laird, born in 1550, who revolutionized mathematics by inventing logarithms. Over the centuries, the tower witnessed notable events including sieges in the 16th century and associations with figures like Mary, Queen of Scots.

Architectural Features and Restorations

Built on an "L" plan, the tower stands five storeys tall with a gabled attic and is constructed of pink sandstone. Its design includes a vaulted basement cellar, a large kitchen with a wide fireplace, and a turnpike spiral staircase ascending through the floors. The main entrance, unusually positioned on the second floor, originally featured a drawbridge. Restoration efforts in the mid-20th century uncovered a seventeenth-century plaster ceiling and preserved intricate Renaissance painted wooden ceilings, considered among Scotland’s earliest examples of such decoration. Later additions included a Gothic-style extension, now mostly removed, and modern corridors connecting the tower to university buildings.

Noteworthy Anecdotes and Surroundings

The tower’s history includes intriguing stories such as accusations of witchcraft linked to meetings held in its upper chambers during the 16th century. The surrounding gardens were extended in the late 16th century, and the tower endured bombardment during political conflicts. Nearby, remnants of a 17th-century gate hint at the estate’s former extent. Today, the tower is surrounded by modern university buildings, yet it retains its medieval charm as a protected historic landmark.

Preservation and Access Considerations

Preserved as a scheduled monument, Merchiston Tower is a protected site within Edinburgh’s urban landscape. Access inside the tower is limited by a narrow turnpike staircase, which may restrict mobility for some visitors.
