The parish church of Saint Tanwg at Llandanwg is situated just behind the beach in the sand dunes just 20 metres above the high tide mark. The church is medieval, probably dating from the 13th century, however there are three 5th to 6th century inscribed stones and two stones with inscribed crosses inside the building which indicates much earlier activity. It has probably been a place of worship since the Age of the Saints, possibly as early as the first part of the 5th century. Much of the churchyard is buried in sand. The churchyard contains the war graves of a Royal Welsh Fusiliers soldier and Royal Garrison Artillery officer of World War I.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
