Located in the Castlegate, the Aberdeen Mercat Cross was built in 1686 by John Montgomery, a local mason, reputedly at the cost of £100. This fine structure comprises a large hexagonal base for a vertical post topped with a white unicorn. The base is highly decorated, including medallions illustrating ten of the Stewart monarchs; namely James I to James V, Mary Queen of Scots, James VI, Charles I and II, and James VII.
The Mercat Cross was traditionally the site of miscellaneous public punishments, together with Royal proclamations.
