The east gable is surmounted by a Classical pediment whose ends and apex are topped by ball-topped obelisk finials. The pediment contains a small oculus. The main window is round-arched and consists of a cluster of five lancet lights while the lancet windows in the gable of either aisle hold three lancet lights. Between the apex of the central window and the pediment is a stone marked 1614, which shows the arms of Edinburgh. Below the central window stands the round-arched former doorway of the East church, now built-up.
