The site remains one of the few examples of a preserved 18th-century royal garden in Lisbon.
Established in 1768, the Jardim Botânico da Ajuda is Portugal’s oldest botanical garden, commissioned by King D. José I. The site is structured on two levels connected by a monumental staircase. The upper level features a structured baroque layout with geometric boxwood hedges and a central stone fountain. The lower level contains greenhouses and a diverse collection of exotic plant species from former Portuguese colonies. It occupies the grounds of the Ajuda National Palace. The garden is managed by the Instituto Superior de Agronomia. It serves as both a public leisure space and a botanical research center. It maintains a distinct 18th-century design reflecting the royal taste of the Pombaline era.

No picking plants or walking on flower beds; quiet behavior is expected as it is a research site.
