Ottagono Alberoni, Military fort in Venice Lagoon, Italy.
The Ottagono Alberoni is an octagonal-shaped military fortress situated on a small island in the Venetian lagoon. Its stone walls were constructed to command the waterways and control passage through this strategic location.
The fort was reinforced during the War of Candia in the 17th century to defend Venice against naval attacks. It subsequently housed a permanent military garrison that remained stationed there for centuries.
The fort embodies Venetian military innovation and how the Republic sought to protect its lagoon waters. It represents an era when such structures were vital to regional defense.
Reaching the island requires boat access, which visitors must arrange through local water transport services. The nearest departure point is at the Alberoni pier, where transport options can be organized.
The octagonal shape was a deliberate architectural choice to optimize cannon fire in all directions. This design allowed a smaller garrison to defend the entire structure more effectively.
