Annexed to the eighteenth-century Palazzo Attems Santa Croce, it originally had an Italian-style layout, with geometric flowerbeds, regularly arranged along the main axis of the building.

This layout was significantly modified after the entire complex became the property of industrialist Gian Cristoforo Ritter, who, in addition to giving the building its current neoclassical appearance, expanded the park following a Romantic-style layout, with curved paths and irregular groves. The construction of the small monopterometric temple, located at the end of the new visual axis, likely dates back to this period. The park was renowned for its prized floral species and exotic trees, including a sequoia. After the complex was sold to the municipality in 1907, the green area was significantly reduced to make room for the construction of Via Barzellini and the Pitteri school.
