Colonia Olivetti, Holiday camp in Marina di Massa, Italy.

Colonia Olivetti is a seaside holiday camp in Marina di Massa, set among pine trees between Via Bondano and Via delle Pinete. Designed by Annibale Fiocchi, it consists of three rectangular blocks—two dormitories and a central services building—linked by porticoed walkways and sun terraces, with pilotis on the ground floor and ribbon windows screened by metal sunshades. A separate infirmary pavilion with stone cladding stands at the south-western corner.

Olivetti commissioned the colony in the mid-1940s for employees' children; architect Annibale Fiocchi's executive plan was approved in autumn 1948. Construction proceeded in stages: refectory and kitchen in 1949, laundry in 1950, first dormitory in 1952, infirmary in 1954–55, second dormitory in 1956–57, with systems completed in 1958. The complex was unused from the early 1990s and was up for sale in the early 2000s.

Inside, the refectory holds a frescoed panel with a marine scene, while the dormitories and the isolation ward carry painted panels, all by Egidio Bonfante. The games room has abstract decorative panels by Marcello Nizzoli, and Ottavio Cascio designed the interiors.

The complex sits in a quadrangular lot between via delle Pinete to the east, via di Bondano a Mare to the south (service entrance), a pedestrian path to the beach to the north and a neighbouring colony to the west. The main building and pavilions stand among pines, palms, holm oaks and privet hedges; the infirmary pavilion at the south-western corner is reached by a pedestrian path.
