This diminutive place measures just 5m by 3.6m making it one of Europe's smallest chapels. It was built in 1877 by Edward Costello, distraught at the early death of his wife Mary. Both husband and wife now rest within the grey limestone interior lit by a single stained-glass window. Their embalmed bodies were placed in lead coffins, which sit on either side of the door. If the door is locked, ask at St George's Heritage Centre for the key.
