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 Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
