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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
