Catedral Metropolitana de la Ciudad de Mexico, dedicated to the Assumption of the Virgin Mary. Its construction began in 1570 and was considered finished only in 1813, including earthquakes and floods.
One curiosity is that we see in the center of the cathedral and its dome an immense pendulum attached to the center. This pendulum is measured on a chart attached to the floor which is the slope of the dome, since the structure is very heavy slowly sinking in the muddy ground of the bed of ancient Lake Texcoco on which the city was built.
