The Gallarus Oratory is a very unique church which may date from the 6th century.
It is built in the shape of an upturned boat.
Built of dry stones there is no roof; instead the stones taper towards the top.
The walls are built of sandstone and are 1.2 metres thick.
They are perfectly fitted together and it is completely waterproof inside.
It is dimly lit, with only a very small window opposite the entrance door (shown).
The church overlooks the harbour at Ard na Caithne (which was known as Smerwick untill quite recently) and is located on the stunning Dingle Peninsula.
