In which region of Italy is this town, shaped like a nine-pointed star?

This is Palmanova, a place that is listed as one of “I borghi più belli d'Italia” ("The most beautiful villages of Italy"). It is a town and municipality in the regional decentralisation entity of Udine in the northeastern region of Friuli-Venezia Giulia. The town is an example of a star fort of the late Renaissance, built up by the Venetian Republic in 1593.

On 7 October 1593, the Venetian Republic founded a revolutionary new kind of settlement: Palmanova. The town’s founding date commemorated the victory of the Christian forces (supplied primarily by the Italian states and the Spanish kingdom) over the Ottoman Turks in the Battle of Lepanto in 1571, during the War of Cyprus. Also honoured on 7 October was Saint Justina of Padua, chosen as Palmanova's patron saint.

Using all the latest military innovations of the 16th century, this small town was a fortress in the shape of a nine-pointed star, designed by Vincenzo Scamozzi. Between the points of the star, ramparts protruded so that the points could defend each other. A moat surrounded the town, and three large, guarded gates allowed entry. The construction of the first circle, with a total circumference of seven kilometres (four miles), took thirty years.
