This is one of my favourite words... but you will see why.
E is for Eglos which is Cornish for Church, and the Welsh equivalent is eglwys
There is a village called Lanteglos (actually there are two of them one at Fowey the other at Camelford) and it is the latter that this entry comes from :
Lanteglos church stands in a small valley south west of Camelford. Today there is no sizeable settlement surrounding the church and its relative isolation may indicate an earlier mediæval monastery site superseded by the Domesday Manor of Helstone whose former deer park lies to the south of the church.
