Sprawling across a hill on the eastern edge of the San Juan Islet, Castillo de San Cristobal was built by the Spanish to protect the city from being attacked by land, and it remains the largest fortification ever built in the New World. It consists of three different levels, and visitors are welcome to take a self-guided tour with the help of a brochure and the many signs dotted throughout the grounds. The site is open every day between 9 a.m. and 6 p.m., and admission is free for visitors under the age of 15.
