Britain's Queen Elizabeth's art gallery was on the IRA death list.
Files just released have shown the Irish paramilitary group targeted high-profile London attractions in the 70s - including the gallery at the queen's residence Buckingham Palace - in a two-year bombing campaign.
The hit list was found in a London flat raided by police in December 1975 which was occupied by the IRA's Balcome Street gang and used as a Republican bomb factory.
The four-man unit - Martin O'Connell, Edward Butler, Harry Duggan and Hugh Doherty - carried out a series of bombings and murders in the 70s.
The gang was captured by police on 12 December 1975 after a six-day siege at a flat in Balcome Street, central London, and officers came across the list.
The then Prime Minister Harold Wilson was told about the find, but was told that it did not represent a "death list".
Large sections of the document - which was 86 pages long - have never been made public until now.
In a covering letter to the document, Bill Innes, then private secretary at the Home Office, stressed that it was not a "death list".
He wrote: "It is a compilation of a vast amount of low-grade 'intelligence' material found in the flat, which has yet to be assessed and evaluated, and no significance or meaning can be attached to any of the names on the list."
The Balcome Street four were jailed for life in 1977, but were freed in 1999 under the Good Friday Agreement.
