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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
