The church of St Just is medieval. There are no remains of the early medieval church and only part of the chancel remains from the church built in 1334 which was dedicated on 13 July 1336 by the Bishop of Exeter, John Grandisson. The current building dates from the 15th-century. In 1355 the church was given to Glasney College by Sir John de Beaupre together with the church lands of Lafrowda. Medieval chapels in the parish included a chapel of St Helen at Cape Cornwall and a chapel of St Michael on Chapel Carn Brea.
The church is large and built of regular granite blocks. Both the body of the church and the tower are of the 15th-century and the tower is of three stages. The aisles are built to the same design with alternating windows of two different patterns. The arcades have limestone piers. The font is modern but has been described as 14th-century in date. Two medieval wall paintings remain but they are both heavily restored; one portrays St George and the other a warning to breakers of the Sabbath.
The Selus Stone is thought to date from the late 5th or early 6th-centuries. It bears the Latin inscription Selus Ic Iacet (Selus lies here). This is thought to refer to Salomon of Cornwall, otherwise known as Saint Selevan.
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.
