York Historic Environment Record

Interval Tower S.W. 6. In Museum Gardens N.G. 60055203). Fragments of the core of a wall of the rear compartment are visible in St. Leonard's Hospital, behind an inserted fireplace. The S.E. half of the projecting front of the tower has recently been excavated and is now (1960) exposed. The same excavation established Section (F iii), see p. 21b. Unpublished: information from the excavator, G. F. Willmot.

This projecting polygonal interval tower of the 4th century lies 125½ ft. from the W. Angle Tower and 125 ft. from Interval Tower S.W. 5. The foundations and base of three segments of the front, each some 8 ft. long, have been revealed and fit a six-sided plan. The total projection was some 17 ft. and the total width at the junction with the fortress wall 32 ft. The walls at the base, allowing for a missing inner face, are 6½ ft. thick, probably including a plinth, as at the W. and S. Angle Towers. Their masonry is like that of the fortress wall and of one build with it, but the two foundations abut, for, while the 4th-century fortress wall was built upon the Severan foundations, the tower was a completely new feature with new foundations. These foundations, trench-filled, consist of layers of rubble and mortar similar to the composition of the wallcore and are as deep as the 1st-century ditch, long filled in and forgotten, which the tower straddles. The tower rose out of the side of the wide 4th-century ditch, which here had its scarp strengthened with oak piles.
