St. David's Church, or Llanfaes Church, consists of a chancel, nave, and a tower at the west end in which are six bells. In the aisle and chancel there used to be several stones to the memory of departed. There is a tablet in the church to the memory of the Rev. Theo. Evans, of Llangammarch, who afterwards became vicar of St. David's. This church was last restored in 1859, at a cost of £1,500, and contains a memorial window given by the late Colonel and Mrs. Church Pearce, in memory of their son. In 1808 three-quarters of an acre of land was consecrated for burial ground purposes by the Bishop of St. David's. The parish register dates from the year 1780.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
