Ardtole was formerly the Parish Church of Ardglass and is dedicated to St Nicholas, the patron saint of sailors. The structure is of a characteristic Anglo-Irish parish church of the Middle Ages. The long narrow church seems largely of 15th century date, with a huge east window and opposed north and south doors, one with a draw-bar hole. In 1791 a cross-decorated slab of the Early Christian period was found, showing that perhaps the site has a longer tradition than the surviving remains would suggest. A souterrain was also found south of the church. The early cross slab, now built into the Roman Catholic church at Chapeltown, and the souterrain, suggest Early Christian activity on the hilltop.
The Church sat halfway between the Anglo-Norman settlers and traders of Ardglass and the native Irish of the surrounding area, but was used by both sets of people until the 15th or 16th century. According to tradition some people from Ardglass found the chieftain of the MacCartans in a drunken sleep and fastened his hair to some briars. He avenged this affront with a massacre of the townsmen gathered together for mass in Ardtole Church. This disaster led to the abandonment of the building as a place of worship for Ardglass, probably in the 16th century.References:
Château de Falaise is best known as a castle, where William the Conqueror, the son of Duke Robert of Normandy, was born in about 1028. William went on to conquer England and become king and possession of the castle descended through his heirs until the 13th century when it was captured by King Philip II of France. Possession of the castle changed hands several times during the Hundred Years' War. The castle was deserted during the 17th century. Since 1840 it has been protected as a monument historique.
The castle (12th–13th century), which overlooks the town from a high crag, was formerly the seat of the Dukes of Normandy. The construction was started on the site of an earlier castle in 1123 by Henry I of England, with the 'large keep' (grand donjon). Later was added the 'small keep' (petit donjon). The tower built in the first quarter of the 12th century contained a hall, chapel, and a room for the lord, but no small rooms for a complicated household arrangement; in this way, it was similar to towers at Corfe, Norwich, and Portchester, all in England. In 1202 Arthur I, Duke of Brittany was King John of England's nephew, was imprisoned in Falaise castle's keep. According to contemporaneous chronicler Ralph of Coggeshall, John ordered two of his servants to mutilate the duke. Hugh de Burgh was in charge of guarding Arthur and refused to let him be mutilated, but to demoralise Arthur's supporters was to announce his death. The circumstances of Arthur's death are unclear, though he probably died in 1203.
In about 1207, after having conquered Normandy, Philip II Augustus ordered the building of a new cylindrical keep. It was later named the Talbot Tower (Tour Talbot) after the English commander responsible for its repair during the Hundred Years' War. It is a tall round tower, similar design to the towers built at Gisors and the medieval Louvre.Possession of the castle changed hands several times during the Hundred Years' War. The castle was deserted during the 17th century. Since 1840, Château de Falaise has been recognised as a monument historique by the French Ministry of Culture.
A programme of restoration was carried out between 1870 and 1874. The castle suffered due to bombardment during the Second World War in the battle for the Falaise pocket in 1944, but the three keeps were unscathed.
