Catedral de Nuestra Señora de la Paz
The downtown church, Catedral de Nuestra Señora de la Paz, is a simple, unassuming building near the site of La Paz's first mission, which no longer exists. Built in 1861, it's one of La Paz's oldest buildings, and so no changes can be made, even for restoration. It was built with volcanic stone, the primary available material at the time; inside you can find a modest gilded altar but beautiful stained-glass windows.
