Santander’s serene cathedral comprises two Gothic churches, one above the other. The 14th-century upper church, extensively rebuilt after the 1941 fire, houses the tomb of Marcelino Menéndez Pelayo (1856–1912), a celebrated Santander-born intellectual. Its handome cloister dates from the 15th century. Below lies the 13th-century Iglesia del Santísimo Cristo, where you can view two silver heads containing the skulls of Santander’s patron saints.
