This stately, blue-domed, earthquake-resistant cathedral was completed in 1868 after 86 years of construction. The neoclassical structure inspires both austerity and awe, with its stone floors, colonial paintings, lofty arches, and bursts of gold at its altars. Perhaps the cathedral's most striking feature is the entrance, which is supported by 12 pillars, each of which is inscribed with the names of hundreds of Guatemalans who died or "disappeared" during the civil war. The interior is large and filled with religious icons, carvings, and artworks. You can tour the cathedral in about 20 minutes.
