The chart, then, _reversed_, shows the whole position thus. On our left, the west, is the ruined Kirk o’ Field church, the church yard being bordered, on the north, by the town wall, here running, for a short way, east and west. After the town wall turns at a right angle and runs south to north, it is continued west and east by a short prolongation of some ten yards, having a gate in it. Next, running west to east, are two tall houses, forming the south side of a quadrangle. These Crawford (1646) seems to have regarded as the Provost’s lodgings. The east side of the quadrangle consists of four small houses, as does the north side. The west side of the quadrangle was Darnley’s house. It was in the shape of an inverted L, thus Г. The long limb faced the quadrangle, the short limb touched the town wall, and had a door through it, into the Thieves’ Row. Beyond the Thieves’ Row were gardens, in one of which Darnley’s body and that of his servant, Taylor, were found after the explosion. Mary’s room in the short limb of the Г had a garden door, opening into Darnley’s garden. Behind Darnley’s garden were the grounds of the Black Friars monastery. On the night of the murder Bothwell conveyed the gunpowder into the Black Friars grounds, entering by the gate or through the broken Black Friars wall to the north side of the quadrangle, and thence into Darnley’s garden, and so, by Mary’s garden door, into Mary’s chamber: as the depositions of the accomplices declare.

Town Wall] The whole quadrangle lay amidst wide waste spaces of gardens and trees, with scattered cottages, and with Hamilton House, a hostile house, hard by. Such was the situation of Kirk o’ Field, Church and College quadrangle, as shown by the contemporary plan. The difficulties are caused by the wall, in the chart, running south to north, having Darnley’s house abutting on it at right angles. The old ruined wall, on the other hand, was to the south of the quadrangle, as was the wall of 1647. When or why the wall running from south to north was built, I do not know, possibly after 1559, out of the stones of the Black Friars.[127] The new work was done under James Lindsay, treasurer in 1559, and Luke Wilson, treasurer in 1560. Perhaps the wall running south to north was the work of these two treasurers. At all events, there the wall was, or there it is in the contemporary design, to the confusion of antiquaries, bewildered between the south to north wall of the chart, as given, and the new wall seen in the map of 1647, a wall which was to the south of Kirk o’ Field, while, in the map of 1647, there is no trace of the south to north wall of the chart of 1567.
