Within a few years, the Academy of Fine Arts and the Braidense Library were founded while the astronomical observatory, which was initially just moved into the palace, became the modern Brera Astronomical Observatory while the Brera Botanical Garden was established on the site of the Jesuits' herb garden.
It contains one of the oldest Ginkgo biloba trees in Europe, as well as mature specimens of Firmiana platanifolia, Juglans nigra, Pterocarya fraxinifolia, and Tilia.
