Metro Peñón Viejo is named for the Peñón del Marqués. The famous peak was later renamed, to avoid referring to Hernán Cortés, and called simply the “big old rock.” The station icon represents this rocky hill, and it’s stylized the way that some ancient artists might have depicted it. The hill represented, for many years, the easternmost limits of Mexico City.
By the 1970s, though, Mexico City had spread this far. That not only necessitated Metro Line A, but saw communities grow even far to the east. Today, it’s not the busiest station on the line. About 12,ooo passengers pass through every day.
The Metro Peñón Viejo station is technically on the old land grant, the farmers’ fields, of the town of Santa Martha Acatitla, which lays to the southeast. The Peñón itself, the mountain, is passed by the train. It stands to the northwest of the station in a neighborhood called Colonia El Paraiso. This is fitting as the neighborhood is arguably best known for a small resort and spa popular with local kids and families. The spa provided most of the historical information on the Peñón del Marqués through their own Facebook page.
