Note 5 — Chapter I · THE ORIGIN OF THE UNIVERSITY OF CAMBRIDGE
Reading edition
The castle, ruinous by the middle of the xv c., was quarried to supply stone for King’s College and other university buildings in that and the next century. Edw. III. had quarried it for King’s Hall, and Hen. IV. granted more of the stone for King’s Hall chapel. Finally Mary gave the stone to Sir Robert Huddleston in 1557 for his new house at Sawston: “Hereby that stately structure, anciently the ornament of Cambridge, is at this day reduced next to nothing,” writes Fuller.
