Foro Annonario

The Foro Annonario is a 19th-century market building with 24 Doric columns arranged in a circle, forming a covered gallery around a central marketplace. The brick structure carries classical appeal, and the restored upper level now houses the municipal archives and a public library.

The structure was designed by architect Pietro Ghinelli in 1834 as a brick building to expand trade activities within Senigallia's ancient walls. Its construction marked an economic shift as the city solidified its role as a trade port.

The name Annonario derives from the Roman grain authority, reflecting the site's long connection to food supply. Visitors notice how the marketplace remains active with local shoppers today, maintaining a rhythm of commerce that has lasted nearly two centuries.

The marketplace operates daily with local vendors selling fresh vegetables, fruits, and fish, making it a functioning market space. The covered colonnade provides shelter from sun and rain, keeping the space comfortable regardless of weather.

The covered fish market area under the portico receives direct sunlight only during sunset hours, an effect that once provided natural cooling for the older business operations. This unusual lighting pattern was actually woven into the site's original trading functions.
