Book excerpt: This book tells a new story of the royal castle of Lincoln in the north of England, how it was imposed on the late Anglo-Saxon town, and how it developed over the next 900 years in the hands of the English king or his aristocratic associates, leaving us a surviving monument of three great towers, each with its own biography. Led by FAS Heritage, archaeologists, architectural historians and a large cohort of the general public have combined to produce a revealing and accessible account of the story of Lincoln Castle and a reborn historical attraction for the city of Lincoln.
