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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
