Achallader Castle is a ruined 16th-century tower house. Sir Duncan Campbell of Glen Orchy acquired the castle and surrounding lands through his treachery and betrayal of the Chief of the Mcinleisters in 1587. It is said that when the Fletchers owned Achallader, Sir Duncan Campbell - known as Black Duncan - ordered an English servant (or soldier) to pasture his horse in the Fletchers’ corn. When warned off by the Fletchers - in Gaelic - he did not understand; when he did not remove his horse they shot him. Black Duncan, affecting concern that the Fletcher laird would be hanged for the killing, advised him to flee to France. Before he fled he passed the property to Black Duncan, supposedly until his return, to prevent it being forfeited to the Crown. The Fletchers never recovered the property. The MacGregors burnt the castle in 1603.
In the summer of 1683 a Commission for the settlement of the Highlands, led by Sir William Drummond of Cromlix stayed at the castle, welcoming, among others McIain, the future victim, with his clan, of the massacre of Glencoe. In 1689, with William and Mary now reigning, the McIain’s returning from their victory at Killiecrankie and repulse at Dunkeld, pulled down what they could of the castle. It was never restored.
In June 1691 John, Earl of Breadalbane, empowered by King William to treat with the clans, conferred with the highland chiefs in the ruin of the castle. By a mixture of threats, promises of bribes, and duplicity, he persuaded most of the clans -but not the McIains - to enter a treaty. This included secret provisions, which he later denied, including the right of the chiefs to request relief from their oaths of allegiance from the exiled James VII and II. The promised bribes did not materialise.
The castle formerly rose to three storeys and a garret, well defended by shot-holes. Now only two walls, one with a trace of corbelling, remain, sheltering the farm buildings of Achallader Farm.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
