Forework of Stirling Castle, Stirling

The gatehouse providing entry from the outer defenses to the castle proper was erected by King James IV, and was probably completed around 1506. It originally formed part of a Forework, extending as a curtain wall across the whole width of Castle Hill. At the center is the gatehouse itself, which now stands to less than half its original height.

The round towers at the outer corners rose to conical roofs, with battlements carried around the tops of the towers. These were flanked by more round towers, of which only traces now remain, and mirrored by further rounds at the rear of the gatehouse. The overall design, as drawn by John Slezer in 1693, shows French influence, and has parallels with the forework erected at Linlithgow Palace.

Like the Linlithgow structure, the Forework was probably intended more for show, evoking the "age of chivalry", than for defense, as it would have offered little protection against contemporary artillery. The entrance was via a central passage, flanked by two separate pedestrian passages. This triple arrangement was unusual in its time, and Classical triumphal arches have been suggested as an influence. The gatehouse was dismantled gradually, and was consolidated in its present form in 1810.

At each end of the crenellated curtain wall was a rectangular tower. The west tower, known as the Prince's Tower, probably after Henry, Prince of Scotland, survives to its full height, and is now attached to the later palace. At the east end, the Elphinstone Tower contained a kitchen and possibly an officer's lodging. It was cut down to form a gun battery, probably in the early 18th century when the Outer Defences were rebuilt.

Within the Forework is a courtyard known as the Outer Close. To the south-east are Georgian military buildings; the late 18th-century Main Guard House, and the early 19th-century Fort Major's House. To the west of the Outer Close, the main parts of the castle are arranged around the quadrangular Inner Close: the Royal Palace to the south, the King's Old Building on the west, the Chapel Royal to the north, and the Great Hall to the east
