The Red Tower was built in 1490 by order of Henry VII. Controversially, the job of building the tower was given to the bricklayers rather than the stonemasons who resented this greatly. A bitter feud broke out, which led to the murder of a bricklayer and the trial, for murder, of the wardens of the Masons' Guild. Only the top two thirds of the Tower are now visible above ground.

From Red Tower, walk along the main road for five minutes to meet the next stretch of wall, which begins at Layerthorpe Bridge.
