A church was first raised on this site in Gothic style shortly after the conquest in 1229, but was given a complete makeover in the 18th century, so what you see today is mostly baroque. The unusually simple rough-sandstone facade is a lovely backdrop to the square. Lit by a rose window, the interior has an unusual barrel-vaulted ceiling and extravagant ceiling frescoes; some of the latter have been restored with a heavy hand.
