Efforts to restore a castle in the Western Isles built in 1847 for a rich opium trader have secured £240,000 from the Heritage Lottery Fund (HLF).

A further £2.6m of lottery funds could be awarded to Lews Castle if the restoration project's trust can produce detailed proposals within two years.

Lews Castle in Stornoway was constructed for James Matheson, who made his fortune from the opium trade.

Opium exported from China and India was often mixed with tobacco by smokers.
