Sir James Matheson began it in the 1840s, a few years after buying the whole of Lewis, and Lord Leverhulme later gave it to the people of Stornoway, whose trust still cares for the grounds today.
Inside, the restored ground floor holds the Storehouse Café, and the modern wing beside it is Museum nan Eilean, the islands' own museum, where six of the Lewis Chessmen are on show. Afterwards, head out into the grounds. Paths wind through the trees and along the shore, where otters sometimes hunt among the rocks, to the River Creed, and up Gallows Hill for a view over the town. The museum opens Tuesday to Saturday, and the grounds are open at all hours.
