An attempt to build an elevated walkway along the length of Princes Street involved the planned demolition of the entire street in a radical plan published in the 1960s. The plan was unpopular but before it was abandoned in 1982, seven buildings were removed. The old Boots building at 102 Princes Street, with its series of statues of William Wallace, Robert Burns, Sir Walter Scott and Robert the Bruce, was demolished in 1965. The North British & Mercantile Insurance Company building at number 64 followed. The New Club, designed by William Burn and extended by David Bryce, and the adjacent Life Association of Scotland building by David Rhind and Sir Charles Barry also came down.
