St Trillo, Rhos on Sea
A tiny church with a big view. This is perhaps the smallest of all of the churches on this list and indeed in Britain. It is named after a 6th century Celtic saint and sits over a natural spring which has long been associated for its healing powers. The building is a very simple low stone structure with wide stone buttresses, and at full capacity the church can fit about 6 people within its walls. St Trillo is sited on the coastline of North Wales, affording beautiful views across Penrhyn Bay.
