Spanish rulers built this fortress between 1564 and 1576, and by the time it fell it had become one of the largest in Europe, an elliptical stronghold of travertine stone stretching some five hundred meters along its ridge above the Teramo valley.
Its final chapter made it famous: Bourbon troops held Civitella through a siege lasting from October 26, 1860, until March 20, 1861, three days after the Kingdom of Italy had already been proclaimed elsewhere, making this the last place the Bourbon flag flew anywhere in the peninsula. Restoration between 1975 and 1985 opened the fortress fully to visitors, and it now draws thirty to forty-five thousand people a year to a weapons and maps museum inside walls twinned since 1989 with Salzburg's Hohensalzburg fortress.
