Playfair's Monument, City Observatory, Calton Hill, Edinburgh

Playfair's Monument, located at the City Observatory on Calton Hill in Edinburgh, was designed by William Henry Playfair and constructed between 1825 and 1826. This square-plan memorial features a Greek Doric style and is made of polished ashlar stone. It has a projecting base plinth that supports a podium, which includes a projecting base course chamfered to the upper section. The monument is topped with a moulded cornice and a tetrastyle blind colonnade made up of engaged fluted Greek Doric columns. The entablature is decorated with metopes that are adorned with laurel wreaths, and it culminates in a pyramidal stone roof.

On the southeast elevation, the podium is inscribed with a dedication that translates to: "To John Playfair, the piety of friends, struck by faithful desires, where he himself had once dedicated a temple to his Urania, this monument was erected in 1826, born on the 6th of March 1748, died on the 14th of August 1819."
