The Mercat Cross of Edinburgh stands in Parliament Square next to St Giles' Cathedral, facing the High Street in the Old Town of Edinburgh.
The current Mercat Cross is of Victorian origin, but was built close to the site occupied by the original. The Cross is first mentioned in a charter of 1365 which indicates that it stood about 45 feet (14 m) from the east end of St. Giles'. In 1617 it was moved to a position a few yards (metres) down the High Street now marked by "an octagonal arrangement of cobble stones" (actually setts). This is the position shown on Gordon of Rothiemay's map of 1647 (see external link below).
In 1756, the Cross was demolished and parts of the pillar re-erected in the grounds of Drum House, Gilmerton. A monument now stands there and on it a plaque that reads "Erected in memory of the old Mercat Cross of Edinburgh which stood at The Drum from 1756 to 1866. This Monument was erected November 1882". Five of the eight circular medallions featuring sculpted heads from the understructure of the original cross were eventually secured by Sir Walter Scott who incorporated them into the garden wall of his house at Abbotsford in the Scottish Borders.
In 1866 the pieces of the cross from Drum House were reassembled on a new stepped pedestal on the east side of the north door of St Giles. (That base now supports the Canongate Cross.) Because the pillar had been broken during demolition in 1756, its height was reduced after reassembly from 19.7 to 13.9 feet (6 to 4.25 m) and its girth made thinner. In 1885 it was placed on a new octagonal drum substructure at its current location, 24 feet (7.3 m) south of the original pre-1617 position. This was designed by Sydney Mitchell and paid for by William Gladstone, M.P. for Midlothian from 1880 to 1895, whose father and grandfather hailed from Edinburgh. The sculpted heads on the original cross were replaced by the royal arms of Britain, Scotland, England and Ireland, the burgh arms of Edinburgh, Leith and the Canongate, and the arms of the University.
