The billionaire US property tycoon will be told of plans to revamp Lews Castle near Stornoway on Lewis when he visits the island on Monday.
Mr Trump is heading to Scotland for an inquiry into his proposed £1 billion golf resort.
A spokeswoman for the billionaire confirmed today that he had seen a letter from Western Isles Council regarding the castle and was happy to discuss the plans during his visit.
The A-listed castle was built in 1847 for Sir James Matheson, a trader who purchased the Island of Lewis in 1844.
Western Isles Council hopes to re-develop the castle into a hotel and museum at a cost of £7.5 million.
Mr Trump's spokeswoman said: "He has said he is happy to talk to the local authority about this when he is across on Monday, but he cannot make any promises."
