Inhabited since late Iron Age times (4th-3rd centuries BC), the Tremiti Islands have been a place of confinement since ancient times. Roman emperor
Augustus had his granddaughter
Julia the Younger transferred here, where she died after 20 years. In the Middle Ages, the archipelago was ruled by the
Abbey of Santa Maria a Mare ("Holy Mary on the Sea") at San Nicola island, apparently founded here in the 9th century by
Benedictine monks from
Montecassino. In the 13th century, the abbey had gained its autonomy from the father monastery, and owned lands from the
Biferno to
Trani on the Apulian mainland. After an alleged period of moral decadence, in 1237 the Benedictines were replaced by the
Cistercian order. In 1334 the abbey was sacked by Dalmatian pirates from
Omiš. In 1412 the
Lateran Canons took ownership of the islands and restored the abbey with cisterns and fortifications which withstood the assault of Ottoman ships in 1567. The abbey was suppressed in 1783 by King
Ferdinand IV of Naples, who set up a
penal colony. During the
Napoleonic age the islands were a stronghold of
Joachim Murat's supporters, who resisted a British fleet in 1809. In 1843, to repopulate the islands, King
Ferdinand II of Two Sicilies moved a number of people from
Naples' slums to the islands, who mostly became fishermen. In 1911, about 1,300
Libyans who had resisted Italian colonial rule were confined to Tremiti. After a year, around one-third of them had died, mainly from
typhus.
1930s During the Fascist era, the archipelago continued to perform its function of confinement, detaining, among others,
Amerigo Dumini, and future president of the Republic,
Sandro Pertini. Mussolini had hundreds of homosexuals deported to San Domino, in 1938. No law prohibited homosexuality at the time, and Mussolini also denied its existence, saying, "In Italy, there are only real men". However, suspected or reported homosexuals were rounded up and deported. San Domino had the distinction of being the only internment camp in which all the prisoners were gay. The dormitories were spartan, with no electricity or running water. A bell would ring at 8 p.m. each day, signaling that the men were no longer allowed to be outside. For the remainder of the night, they were locked in their dorm rooms, under police supervision.
2020s In August 2025,
Alice Walton's $300 million yacht Kaos was seen sailing through the islands. The 360-foot Oceanco masterpiece ranks among the largest superyachts ever to visit the Tremiti Islands. ==See also==
