Built between the 14C and the 16C, the Cathedral has all the features of the flamboyant Gothic style. Inside, take time to admire the altarpiece at the high altar, the chapel of the Rey Chasto and the cross- ribbed cloister. When you reach the reconstructed Holy Chamber, built in the reign of Alfonso II in the 9C, you will find an astonishing collection of column-statues (12C), and of course the Treasury, with remarkably fine gold and silver work (9C-12C).
