St Trillo's Chape Smallest Church in UK Possibly?

Take a peek inside this tiny, single-storey chapel by the sea.
Is this the smallest church in Britain? With seats for just six people, it may well be a contender for the title.
Dating to the early 16th century, the chapel may have been built on the site of an older church on the orders of the Cistercian monks at Aberconwy Abbey.
In 1935 the chapel was carefully restored and re-consecrated by William Thomas Havard, Bishsop of St Asaph.
The chapel is dedicated to St Trillo, an early saint from the 6th century with connections to the area.
The altar stands over a natural spring, thought to have been an ancient holy well,
from which water has been used for baptisms in the parish.
