Duart Castle dates back to the 13th century and is the seat of Clan MacLean. In 1647, Duart Castle was attacked and laid siege to by the Argyll government troops of Clan Campbell, but they were defeated and driven off by the Royalist troops of Clan MacLean. In September 1653, a Cromwellian task force of six ships anchored off the castle, but the Macleans had already fled to Tiree. A storm blew up on the 13 September and three ships were lost, including HMS Swan.
In 1678, Archibald Campbell, 9th Earl of Argyll, son of the Marquess of Argyll, successfully invaded the Clan MacLean lands on the Isle of Mull and Sir John Maclean, 4th Baronet fled the castle and withdrew to Cairnbulg Castle, and afterward to Kintail under the protection of the Earl of Seaforth. In 1691 Duart Castle was surrendered by Sir John Maclean, 4th Baronet to Archibald Campbell, 1st Duke of Argyll. The Campbell clan demolished the castle, and the stones from the walls were scattered. Donald Maclean, 5th Laird of Torloisk used some of the stones to build a cottage for his family close to the site of the castle. By 1751 the remains of the castle were abandoned.
Descendants of Archibald Campbell, 1st Duke of Argyll sold the castle in 1801, to MacQuarrie, who then sold it to Carter-Campbell of Possil who kept it as a ruin within the grounds of his own estate to the north, Torosay Castle. He later sold his Torosay Estate which now included the ruins of Castle Duart to A. C. Guthrie in 1865. On 11 September 1911, the ruin was separated from the rest of the Torosay Estate and was bought by Sir Fitzroy Donald Maclean, the 26th Chief of the Clan MacLean and restored.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.
