The Orto Botanico di Bergamo "Lorenzo Rota" (1,357 m²) is a botanical garden located at the top of a long stairway from Scaletta di Colle Aperto, Bergamo, Lombardy, Italy. It is open daily during the warmer months.
The garden was established in 1972, and named in honor of physician and botanist Lorenzo Rota. It was at first predominantly an alpine garden, but after 1989 began collaboration with the Museum of Natural Sciences and broadened its collection. In 1993, the garden became an integral part of the museum.
