Sé Nova

The landmark 'new' cathedral, started by the Jesuits in 1598 and completed a century later, dominates the square of the same name high in the old town. Its two-tier white facade gives onto a cavernous interior adorned with gilt side panels and an ornate baroque altarpiece. It also features a gallery of reliquaries featuring bones and worse from minor saints and bishops, including St Francis Xavier and St Luke (so it's claimed!).
