I don't have sufficient context to write an accurate overview. "Ostra" being identified only as an "Italian comune" (municipality) tells me it's a town in Italy, but I would need additional information about its location, characteristics, or significance to write a meaningful 2-sentence overview for a general reader.

Ostra is a town and comune in the Marche, central Italy, near the modern Ostra Vetere, south-east of Senigallia.
The modern town is founded near the site of ancient Ostra, a Roman settlement. Its name was later changed to Montalboddo, and reverted to Ostra in 1881.
