Mexico marks Revolution Day on Monday, November 16, the public holiday that remembers the start of the Mexican Revolution on November 20.

It began as an official government holiday and is kept every year on the date set by law. The day honors the uprising that broke out in 1910 and turned into a long struggle across the country. Among the cameras worth a look are the Basilica of Our Lady of Guadalupe in Mexico City and Popocatépetl in the State of Mexico, where the volcano rises as the country's second-highest mountain at 5,426 meters.

Open the Basilica camera for a view of one of Mexico's most important Catholic sites, then switch to Popocatépetl to watch for clear air or a plume over the volcanic ridge. The Cozumel Pier and Playa Condesa cameras can show the Caribbean coast at a holiday pace, while Ciudad Juárez is the place to watch for movement at the border crossings that link Mexico and El Paso.
