Casa del Lago Juan José Arreola, Cultural center in Miguel Hidalgo, Mexico.

Casa del Lago UNAM is a cultural center on the shore of Lago Mayor in Chapultepec Park, with its main entrance on Calle Reforma. The early-20th-century house was commissioned by Porfirio Díaz as a summer residence and later became the first off-campus cultural center of UNAM in 1959, directed by Juan José Arreola. Its rooms host exhibitions, performances, cinema and workshops.

The building was begun in 1906 and opened on 30 April 1908 as the headquarters of Mexico's first Automobile Club, built by order of Porfirio Díaz as a summer residence. In 1911, after the Revolution, Francisco I. Madero's government transferred it to the Nation and named it Casa del Lago. It later housed the Dirección de Estudios Biológicos and, from 1929, UNAM's Institute of Biology until 1959.

The name Casa del Lago dates from 1911, when Francisco I. Madero's government transferred the building to the Nation. Its program revived "Poesía en voz alta", the poetry reading cycle begun shortly after 1959, now a festival linking poets such as the decimistas jarochos with younger Mexican writers. Chess tournaments promoted by Juan José Arreola are still held annually.

The main entrance is on Calle Reforma, at the edge of Lago Mayor in Chapultepec Forest. The building sits beside the lake, so visitors approach on foot through the park; the Castillo de Chapultepec is visible across the water. The center opened on 10 May 1959 and its formal inauguration was held on 15 September of that year.

The building began construction in 1906 and opened on 30 April 1908 as the headquarters of Mexico's first Automobile Club. In 2002, by agreement of rector Juan Ramón de la Fuente, it took the name of its founding director, Juan José Arreola.
