St. Illtyd's Church is located in the almost secretive village of Ilston, reached only via winding narrow lanes or woodland walks. The most dominant feature of the church is its huge tower, topped with its battlemented saddle-backed roof and the ancient yew tree which grows at its side and is reputed to be over six hundred years old.
Whilst the church looks antiquated, the 13th Century building was, in fact, rather extensively renovated during the 19th Century. most of the church's current features date from this later period although one of the three church bells date from as far back as the 15th Century.
The church is usually kept lock except for its services.
