Salisbury is dominated by the towering cathedral, a soaring hymn in stone. It is unique among cathedrals in that it was conceived and built as a whole in the amazingly short span of 38 years (1220–58). The spire, added in 1320, is the tallest in England and a miraculous feat of medieval engineering—even though the point, 404 feet above the ground, is 2½ feet off vertical. The excellent model of the cathedral in the north nave aisle, directly in front of you as you enter, shows the building about 20 years into construction, and makes clear the ambition of Salisbury's medieval builders. For all their sophistication, the height and immense weight of the great spire have always posed structural problems. In the late 17th century, Sir Christopher Wren was summoned from London to strengthen the spire, and in the mid-19th century Sir George Gilbert Scott, the leading Victorian Gothicist who designed the Houses of Parliament, undertook a major program of restoration. He also initiated a clearing out of the interior and removed some less-than-sympathetic 18th-century alterations, returning a more authentically Gothic feel. The spartan interior is enlivened by the remarkable lancet windows and sculpted tombs of crusaders and other medieval notables. Next to the cathedral model in the north aisle is a medieval clock—probably the oldest working mechanism in Europe, if not the world—made in 1386 (there are late-morning demonstrations).
The cloisters are the largest in England, and the octagonal Chapter House contains a marvelous 13th-century frieze showing scenes from the Old Testament. Here you can also see one of the four original copies of the Magna Carta, the charter of rights the English barons forced King John to accept in 1215; it was sent here for safekeeping in the 13th century.
There are bookable tours of the Tower (332 steps up) and the Library (which dates from 1445 and has more than 10,000 books, some 800 years old), as well as free tours of the floor monuments, the stained glass windows, and the Stonemasonry Works, where you can view stone carvers at work. For a peaceful break, the café in the cloister serves freshly baked cakes and pastries, plus hot lunches.
