The Clock Tower
The completion of the gateway tower on the north face took some years. In December 1644 the Governors drew up a contract with William Aytoun to add 22 feet to the height of the tower, with two great windows on each side, but this work was not carried out.
The Hospital minutes for 3rd May 1675 indicate that the master mason Robert Mylne, nephew of John Mylne, was "to think on a drawing" to complete the Tower and report back to the Governors. Nothing was done for another eighteen years but on 6th March 1693 Robert Mylne did present drawings, which he agreed to build for 3,100 merks. This was done, and to this day the octagonal cupola with shell niches and a stone dome dominates the north face of the building.
