To the untrained eye, this monument looks like a random pile of rocks. In a way, that is indeed what it is, as it’s a cairn, a landmark constructed with irregular stones. There is no signage or posting to provide historical context. Instead, one has to dig deeper to realize these stones are the marker of a sinister and unscrupulous story.

In 1720, a surgeon named Nichol Muschat lured his wife Ailie into Holyrood Park and killed her. His previous attempts to poison her, frame her for adultery, as well as asking a friend to knock her off were not successful. Muschat confessed to the crime and, according to court documents, said he killed the woman because he had simply grown weary of her.  

Mushcat was hanged in the Grassmarket, a traditional place for executions in Edinburgh, and a cairn was erected in his murdered wife’s memory, though unfortunately, the guidebooks that mention the cairn fail to mention and preserve her name. The initial cairn was constructed in the traditional Scottish fashion closer to where the actual incident took place, southwest of Saint Anthony's Chapel. Over the years, people would add stones to the growing pile of rocks.

This cairn was created in the 1800s after the original one was removed. Legend says its placement made it so King George IV could view the memorial on his visit to Holyrood Palace.
