The Walt Disney World version of the Pirates of the Caribbean attraction would be housed in a Spanish fortress, much like the show. Originally, the building was known as El Castillo (The Castle), an ancient Spanish citadel. Guarded by the Caribbean watchtower Torre del Sol, the attraction is housed in a golden Spanish fort called Castillo Del Morro, inspired by Castillo de San Felipe del Morro, a 16th-century citadel located in San Juan, Puerto Rico.
