Tenente Siqueira Campos Park is located on Avenida Paulista, in the western part of the city. The site is also known as Trianon Park, a name derived from its association with a belvedere that once stood on the opposite side of the same avenue and was demolished to make way for the construction of MASP (São Paulo Museum of Art). The park's grounds were purchased by the municipal government in the early 20th century and featured landscape designs by Paul Villon and Barry Parker.
