The 500 block was the site of the Jockey Club, designed by Manuel Turner and completed in 1897. Founded in 1882 by future President Carlos Pellegrini, the institution governed horse racing in Argentina, and built the Palermo and San Isidro racecourses. An incident on April 15, 1953, in which bombs were detonated at the Plaza de Mayo during one of President Juan Perón's many rallies, resulted in the destruction of the Beaux-Arts landmark by enraged Peronists, who viewed the aristocratic Jockey Club as a center of anti-Peronism. The lot lay empty until the construction of Galería Jardín (1976), an office and retail complex designed by Mario Roberto Álvarez in a belated International Style. The complex includes several levels of shops, a basement for offices and two high-rise towers, one of which is residential. Its retail section is known for its selection of consumer electronics and computer equipment.
