The oldest continuously inhabited European city in the Americas (founded by Hernán Cortés on Good Friday 1519), where the San Juan de Ulúa island fortress (1568) guarded the silver fleet that shipped the treasure of the New Spain viceroyalty to Seville for three centuries, where the son jarocho music (the African-Spanish-indigenous synthesis from which "La Bamba" derives) plays continuously under the portales of the Zócalo, and where El Tajín (230 km north — the Totonac pyramid complex with the Pyramid of the Niches (365 niches for 365 days) and 17 ballcourts) is the most important Gulf Coast pre-Columbian site in Mexico.
