One of the most prominent plazas is the Plaza del Populo, considered the most beautiful plaza in the city. It is also called Plaza de los Leones (Lions square) because it has a central fountain surrounded by lion statues. The Fountain of the Lions was brought from the nearby Roman city of Castulo. There is a sculpture of a woman in the middle of the fountain that represents Imilce, the Iberian wife of Hannibal. There is also the Villalar Arch, which as constructed to remember the victory of Carlos V against the Comuneros in the Battle of Villalar in 1521. The Jaen Gate was constructed in 1526 to honor the visit of Carlos V. Beside the square is the Casa del Populo, a building done in the Plateresque style that is now used as the Tourism Office. This building was constructed between 1535 and 1540. Beside this building is the old slaughterhouse from the 16th century, with its large imperial coat of arms. This building is now used to house the archives of the city and has a museum.
