In the early 1910s, where today is located the MASP it was constructed a belvedere by an architect design Ramos de Azevedo, who became known as Trianon. During the 1920s and 30s, frequented by intellectuals São Paulo, the park and the belvedere became a symbol of the richness of the Paulista elite formed a harmonious and integrated whole.

Its vegetation consists of remnants of the Atlantic Forest. Noteworthy are great examples of araribá pink, cinnamon-scrapers, cedar, jequitibá, ironwood, sapopemba, sapucaia, plus Abiurana, camboatás, guaraiúva and Tapia-guaçu.

In the understory there alien species introduced as palm-of-range-of-china and seafórtia and native species planted for floristic enrichment. Have been recorded 135 species, of which 8 are endangered as cabreúva the chichá and palm-jussara. 

On the weekends, it is worth visiting the "Hippie Market".  You will see a lot of street vendors selling brazilian handmade goods, and under the museum MASP, a lot of people selling vintage goods. It is very interesting and highly recommended.

Avoid the Trianon Park at night time especially for tourists, pickpockets are known to frequent that park.
