Much of York's ancient walls still survive; they are punctuated by four main gatehouses (referred to as "bars"). Bootham Bar has some of the oldest surviving stonework – dating to the 11th century A.D. It was built almost exactly on the site of the northwestern gate of Eboracum, the Roman settlement that evolved into York. This view, taken from Exhibition Square, shows York Minster, the city's famous cathedral, in the background.
