Knock Castle, also known as Caisteal Uaine or Caisteal Camus, stands as one of Sleat's most atmospheric ruins. Set atop the eastern side of Knock Bay with sweeping views over the Sound of Sleat, it combines centuries of clan conflict with even older origins. The site was once home to an Iron Age fort, Dun Thoravaig, before a 15th-century keep rose here-built by the MacLeods, captured and recaptured during Skye's turbulent clan history, and eventually taken over by the MacDonalds of Sleat. Today the ruin is a quiet, striking reminder of the island's layered past and one of the top sights in the Isle of Skye for travellers who enjoy off-the-beaten-track historic sites.

Though the castle is in heavy decay, its lone surviving window and fragments of later additions stand against the wind, evoking the tumult of centuries. This spot is one of the best places to see in the Isle of Skye if you appreciate remote ruins with dramatic settings and haunting folklore.

History and Significance of Knock Castle

Knock Castle occupies a site of long strategic value. Before the medieval keep existed, an Iron Age fort, Dun Thoravaig, guarded this headland. In the 1300s, the MacLeods built a tower here to secure the Sleat coastline, but by the late 15th century the MacDonalds gained control of the peninsula, capturing the castle along with surrounding lands.

In 1431, James I's forces seized Knock Castle during his campaign to assert royal power over the Lords of the Isles. For decades afterward, the stronghold passed back and forth between the MacLeods and MacDonalds as each clan fought for dominance in Sleat. The MacDonalds remodelled the castle in 1596, but its fate was sealed by the end of the 17th century: by 1689 it was abandoned, its stone eventually quarried for nearby farms and homes.

Knock Castle is also steeped in folklore. Tradition speaks of a Green Lady-or glaistig-who watches over the family tied to the castle, appearing joyful when good fortune approaches and weeping in times of sorrow. Another spirit, a gruagach, was said to care for the livestock. These stories add an otherworldly dimension to the ruin's already dramatic location.

Things to See and Do in Knock Castle

Although heavily ruined, Knock Castle still offers glimpses of its medieval form. The most notable surviving feature is a tall window section from the 15th-century keep, rising above the collapsed masonry around it. Walking the site allows you to trace the outline of the original tower and the later additions made by the MacDonalds.

Stand near the edges of the headland to take in the steep cliffs that guard three sides of the site. The views across Knock Bay and toward the Sound of Sleat are spectacular on a clear day. Visitors who enjoy ruined castles will find this a rewarding, atmospheric stop-one of the things to do in the Isle of Skye that feels far removed from the busier northern attractions.
