Over 200 keeills once scattered across the Isle of Man — tiny stone chapels, about 5 metres by 3 metres, with walls that were “unnecessarily massive for such comparatively small enclosures.” One door. One window. An altar against the eastern wall. Almost always a spring or stream nearby.

They were built by individual holy men who chose to live among the people and serve local families. One keeill per treen was the general pattern.

Find a patch of ground and build your own keeill to scale using stones, sticks, or whatever you can find. Measure out 5m × 3m first — you’ll be surprised how small it is.

Put your door on the west side. Your altar goes against the east wall. Is there water nearby? The holy men always built near water.
