The City Hall of Poseidonia, also known as Villa Tsiropina, is one of the most elegant historic buildings in Dellagrazia. Built in 1916 as a summer residence, it reflects the refined lifestyle of Syros’ aristocratic past.

The villa features reception rooms, lounges, dining spaces and decorative details that highlight its architectural character. Surrounded by gardens, it preserves the atmosphere of a different era.

Today, the building has been carefully restored and functions as the City Hall of Poseidonia, hosting cultural events, exhibitions and local activities.
