Palazzo della Pantanella a Piazza della Bocca della Verità, Industrial complex near Bocca della Verità, Rome, Italy

Palazzo della Pantanella at Piazza della Bocca della Verità is a building with clear, rational architecture featuring large windows and symmetrical facades. Its structure follows the style of late 1800s industrial buildings with functional, geometric design.

Built between 1878 and 1881 under Michelangelo Pantanella's direction, the building was Rome's first pasta factory. The operation relocated in 1929, and the structure took on new roles in the city.

The building shows Rome's shift from an ancient circus site to an industrial district in the 1800s. The factory was part of a new era when large production plants shaped and changed the city's character.

The building faces Piazza della Bocca della Verità on Via dei Cerchi, at the northwest end of the Circo Massimo toward the Tiber. The main block holds municipal offices, including the electoral office, while the rear side facing the Circo Massimo has housed the Rome Opera's costume and set stores since 1931. Both parts are working facilities, so visits are not open to the public.

During renovation work, an ancient Mithraeum was discovered beneath the building, an underground temple dedicated to the god Mithras. This hidden chamber dates to a time long before the factory itself was built.
