Kisimul Castle
Kisimul Castle, seat of the chief of the Macneils of Barra, tells us of the nature of Gaelic lordship in the Middle Ages. Caisteal Chiosmuil, the island stronghold’s Gaelic name, means ‘castle of the rock of the small bay’.
It’s said that the Macneils settled in Barra in the 11th century, but it was only in 1427 that Gilleonan Macneil was recorded as the first lord. He probably built the castle that dominates the rocky islet, and in its shadow a crew house for his personal galley and crew.
The Macneils were a seafaring clan. A descendant, ‘Ruari the Turbulent’, was arrested for piracy of an English ship during James VI’s reign in the later 1500s.
The Macneils of Barra
The Macneils of Barra claimed Irish descent from the legendary Niall of the Nine Hostages, high king of Ireland in the 5th century and great-grandfather of St Columba.
By the 1400s, their clan chief was part of an elite group of lesser lords who were members of the Council of the Isles. This body advised the MacDonalds, Lords of the Isles, usually meeting at Finlaggan, on Islay.
The Macneils didn’t emerge as lords of Barra until Lord Alexander MacDonald granted the island to Gilleonan Macneil in 1427 – but they may have had some control over it in earlier medieval times.
Heavy debts forced the Macneil chiefs to sell Barra in 1838. But a descendant, Robert Lister Macneil, the 45th Chief, bought the estate in 1937, and set about restoring his ancestral seat. It passed into state care in 2000.
An island stronghold
The castle, built in the 1400s, began as a three‑storey tower house where the clan chief lived. A curtain wall surrounded the rocky island and enclosed a small courtyard with several supporting buildings.
These included a:
feasting hall
chapel
tanist’s (heir’s) house
watchman’s house
Most of these buildings were restored in the 1900s, with the tanist’s house becoming the MacNeil family home.
A well near the postern gate draws fresh water from an underground seam. Outside the curtain wall, by the original landing place, you can still see the foundations of the crew house, where the sailors who served the chief’s galley once lived.
