This district has many historical buildings, such as the Santa Ana Church and the remains of the San Jorge Castle. The old quarter of the district offers a panoramic view of Seville's city centre. At the north of the district is the island of La Cartuja, a research and development park, site of Expo 92, from which some buildings were kept. The Isla Mágica amusement park is on the island, as is the 60,000-seater Estadio de La Cartuja, built for Seville's unsuccessful bids for the 2000 and 2004 Summer Olympics.
