Mexico’s largest public square is actually five interconnected plazas, punctuated by Monterrey’s most famous landmark, the terra cotta-colored, 70m (230-ft) tall—but just 2m (6.5 ft) thick—Faro de Comercio, which sweeps its green laser over the city at night. Take advantage of the many gardens and green spaces to rest after a day spent viewing Monterrey’s most important buildings, from the 18th-century cathedral to the modern concrete Palacio Municipal (City Hall).
