The Former Locomotive Depot of Sant'Erasmo, the current home of the Ecomuseum, was built in 1886 as part of the Sant'Erasmo railway station complex, the terminus of the Palermo-Corleone-San Carlo line, the first narrow-gauge railway built in Sicily.
It is a beautiful example of industrial archeology, characterized by a single-aisle pavilion supported by cast-iron pillars with capitals decorated in Art Nouveau style. Its category and architectural quality make it unique in the Palermo area.

The pavilion is surrounded by a freely accessible botanical garden that illustrates the landscapes traversed by the Oreto River.
The garden houses plant collections that represent both local ecology and the city's historical memory and emotional ties.
A space to care for and enjoy together, a place to rest, to play in safety, to meditate, and where to learn to observe and listen to those, human or not, who have become invisible to most.
