Gallarus Oratory, in Ballydavid County Kerry, was built between the seventh and eighth century and is the best preserved early Christian church in Ireland. It represents the apogee of dry-stone corbelling, using techniques first developed by Neolithic tomb makers. The stones were laid at a slight angle, lower on the outside then the inside to allow water to run off.
According to local legend, if a person climbs out of the oratory via the window, their soul will be cleansed. This is, however, physically impossible, because the window is approximately 18cm in length and 12cm in width.
Gallarus Oratory Visitor Centre is located alongside Gallarus Oratory. The centre offers visitors the opportunity to explore Gallarus Oratory and also see a audio visual display of the surrounding area. There is a shop offering souvenirs and some refreshments located in the main centre.
