Llanwinio (Carmarthenshire)
When the attempt was first made to build this church, everything put up in the day fell down in the night, till at last the builder threw his hammer into the air.
The church was then built on the spot where the hammer fell and the work progressed without further hindrance.
In this story we do not hear of a spirit removing the material, but it is evident that it was believed that the falling down in the night of what was put up in the day, was caused by some supernatural agency.
