Why come
Gradisca d'Isonzo sits on the right bank of the Isonzo, ten kilometers downriver from Gorizia. The Venetian Republic built it from scratch starting in 1479 as a frontier bastion against Ottoman raids that had reached Friuli the previous decade. The fortification consumed twenty years and the advice of Leonardo da Vinci, sent here by the Senate in 1500 to redesign the artillery defenses.
The result was a walled town twenty meters high, ringed by seven towers and a wide moat, with the river itself diverted into the defenses. Maximilian I took it for the Habsburgs in 1511 during the War of the League of Cambrai, and it stayed in Austrian hands as the seat of the Principesca Contea di Gorizia e Gradisca for the next four centuries. The town that grew inside the walls is Baroque: the Palazzo Torriani, the Loggia dei Mercanti, the Casa de Fin, all built under the Habsburgs.
Casanova passed through in 1773. Today the walls, towers, and grid still hold.
