---

Castello di Gradisca d’Isonzo is a historic fortress in the town of Gradisca d’Isonzo, built by the Venetians in the late 15th century to defend their eastern frontier.

Thanks to its strategic location along the Isonzo River, it became an important military stronghold and later passed under Habsburg control, remaining a key defensive site for centuries. Although parts of the original structure were modified or damaged over time, the castle remains a prominent landmark that reflects the region’s complex history between Venetian and Austrian rule.

Today, it stands as a symbol of Gradisca d’Isonzo’s heritage and offers visitors insight into the area's military and cultural past.
