"St Winifred's church lies at the heart of the small village of Gwytherin in a remote part of Conwy. It has a long history associated with St Winefride, but the present church was built in the later 19thC and, an old chest apart, contains nothing of an earlier date. The churchyard is an irregular shape but is notable for four standing stones in a line, the westernmost of which is an early medieval pillar stone, and some ledgers of the late 17thC/early 18thC. ... Parts of the following description are quoted from the 1986 publication The Buildings of Wales: Clwyd by Edward Hubbard" SEE http://www.cpat.demon.co.uk/projects/longer/churches/conwy/16790.htm
