San Pietro in Cerro

San Pietro in Cerro is a small municipality located in the Province of Piacenza within the Emilia-Romagna region of northern Italy. Situated approximately 20 kilometers east of Piacenza and 120 kilometers northwest of Bologna, the town lies in a strategic position bordering the communities of Caorso, Cortemaggiore, Monticelli d'Ongina, and Villanova sull'Arda. As of late 2004, the commune covered an area of 27.5 square kilometers and supported a population of 962 residents. The local demographic history reveals a gradual decline over the last century, dropping from a peak of over 2,500 inhabitants in the early 1920s to its current size, reflecting broader rural migration trends in the area.

The provided text does not contain specific details regarding a castle structure, including its year of construction, architectural style, or current condition. While the name San Pietro in Cerro often suggests historical religious or fortified origins common to the region, the available source material focuses exclusively on administrative data, geographic coordinates, and population statistics rather than architectural heritage. Consequently, no information can be extracted about a specific castle's historical significance, design features, or modern usage from this document. The content serves primarily as a geographic and demographic profile of the comune itself rather than a description of a particular historic monument.

For visitors or researchers interested in the site, the town operates as a functioning local government entity with an official online presence. The absence of explicit mentions of a castle in this specific dataset implies that any such structure may be minor, integrated into the urban fabric without distinct fame, or simply not detailed in this brief encyclopedia entry. Those seeking information on specific fortifications would need to consult specialized architectural records or local tourism guides, as the current text limits its scope to the municipal boundaries, leadership, and statistical evolution of the community.
