At the centre of the city is Quimper's Gothic cathedral with its distinctive dip in the middle where it was built to conform to the land, said to symbolise Christ's inclined head as he was dying on the cross. Construction began in 1239, but the cathedral's dramatic twin spires weren't added until the 19th century. High on the west facade, look out for an equestrian statue of King Gradlon, the city's mythical 5th-century founder.
