Basilica of Our Lady of Guadalupe

This guide to the Basilica of Our Lady of Guadalupe in Mexico City opens with the mismatch between the building's official ten-thousand-seat capacity and the crowds of hundreds of thousands who show up every December twelfth. It traces the older basilica that sank into Mexico City's soft lakebed clay, and how five architects led by Pedro Ramirez Vazquez threw out interior columns for one vast concrete roof so every pilgrim could see the same image. Stand almost anywhere under the copper dome and notice how little blocks your view.
