This twin-towered baroque church was completed in 1719 under João V. The spectacular facade was completed after the 1755 earthquake. Brazilian gold paid for it, and the interior is gilded to the extreme. The numerous cherubs seem comparatively serious and sober, no doubt contemplating the ghoulish attraction behind the church: the 19th-century Capela dos Ossos, built from the bones and skulls of over 1000 monks as a blackly reverent reminder of earthly impermanence. It's quite a sight.
