Kilmichael is believed to be the oldest house on the isle of Arran. It is certainly among the richest in its historic associations. Situated at the heart of grounds granted to the forebears of its builders by King Robert the Bruce in 1307, it occupies a spot known to have been inhabited long before that, indeed the name Kilmichael indicates the site of one of the earliest Christian missionary cells, dedicated to St. Michael.

By the middle of the 16th century there were just two principal landowners on the island, the Dukes of Hamilton at the castle and the Fullartons of Kilmichael. No doubt to reflect the family's prominence, the estate was improved in Victoria's time by the addition of a lodge with gates and, inside the house, a tiny, private, family chapel.

For all its proud history and its description in the title deeds as a fine Scottish Mansion House, it is actually quite small and has a charming intimacy about it which complements these grand associations.

Kilmichael House is listed as a building of historic and architectural significance.
