Assos Castle

Assos Castle is a Venetian fortress built atop a rocky hill on the Greek island of Cephalonia, commanding views over Agia Kyriaki bay. The fortified compound covers a broad area with defensive walls and contains various historical structures from its time as a regional stronghold.

A Venetian architect named Marino Gentillini designed and built this fortress between 1593 and 1596 as a defense against pirates and Turkish attacks in the region. Over the following centuries, the structure changed hands and purposes, eventually becoming a prison facility.

The castle displays Venetian rule through the Lion of Saint Mark carved at its entrance. Inside, visitors find remains of a Catholic chapel and former administrative buildings that reflect the long Venetian presence on the island.

The site is reachable through two entrance gates using either paved pathways or walking trails through olive groves. Plan for a half-day visit to explore the interior at a relaxed pace and enjoy the surrounding views without feeling rushed.

The fortress was repurposed as a prison after 1920 and later held political detainees following World War Two. This shift from military stronghold to detention center left its mark on how the space is organized and experienced today.
