The church in Llanfaglan, St Baglan's (Grid reference ) stands alone in the middle of a field and is now owned by the Friends of Friendless Churches. In 2005, it was discovered that the church and the older part of the cemetery were part of a pentagonal enclosure. The period of this enclosure isn't known as it is the only one of this type know of in Europe up to now. A 5th or 6th Century gravestone inscribed with Fili Lovernii Anatemori, has been reused as a lintel over the door. This was the gravestone of Anatemarios, mab Loverniws. Although the Christian church probably dates from the 13th century, additions date from the 17th century as do the internal fittings. The church remains consecrated and is still in occasional use.
The church is usually open during the European heritage Open Door weekends in September, where a local historian is on hand to provide visitors with the history of the church, in either Welsh or English.
