Fodor's Expert Review Hereford Cathedral

Built of local red sandstone, Hereford Cathedral is a treasure trove of historical artifacts, including Mappa Mundi, the largest medieval map to survive in the world, and the largest chained library in Britain (a sort of medieval security system), which still has all its locks and chains intact. The cathedral itself retains a large central tower, and while much of the interior was restored in the 19th century, original 11th-century Norman features remain, including many intricate stone carvings. There are some exquisite contemporary stained-glass windows in the Audley Chapel and a 12th-century chair that is one of the oldest pieces of furniture in the country and was reputedly used by King Stephen (1092–1154). The Mappa Mundi is undoubtedly the biggest draw here. Drawn in about 1300, it’s a fascinating glimpse of how the medieval mind viewed the world: Jerusalem is shown dead center, the Garden of Eden at the edge, Europe and Africa are the wrong way round—and, of course, there are no Americas. In addition to land masses, the map details 500 individual drawings, including cities, Biblical stories, mythical creatures, and images of how people in different corners of the globe were thought to look—the last two frequently overlapping in a wildly imaginative fashion.

The map can be found just outside the Chained Library, which contains some 1,500 books, among them an 8th-century copy of the Four Gospels. Chained libraries, in which books were attached to cupboards to discourage theft, are extremely rare: they date from medieval times when books were as precious as gold. The cathedral also holds a copy of the 1217 revision of the Magna Carta. Tours of the cathedral (without the library and Mappa Mundi, which both require an extra fee, though volunteers are on hand to answer your questions) run daily throughout the year (except Sundays). Garden tours run in summer and tower tours on Wednesdays and Saturdays.
