There was a fire in the city in 1141 during the Rout of Winchester. In the 14th century, William of Wykeham played a role in the city's restoration. As Bishop of Winchester he was responsible for much of the current structure of the cathedral, and he founded the still extant public school Winchester College. During the Middle Ages, the city was an important centre of the wool trade, before going into a slow decline. The curfew bell in the bell tower (near the clock in the picture), still sounds at 8:00 pm each evening.
