Embarcadero de Mineral de Río Tinto
An odd legacy of the area's mining history, this impressive iron pier curves out into the Odiel estuary about 500m south of the port. It was built for the Río Tinto company in the 1870s. Equipped with boardwalks on the upper and lower levels, it makes for a delightful stroll to admire the harbor and ships. It's about 1km southwest of the Plaza de las Monjas.
