The Abbey of Santa Maria a Mare was a monastery on the island of San Nicola in the Tremiti Islands off the northern coast of the Gargano Peninsula in Italy from the 9th century until 1782.
According to Cardinal Leo Marsicanus, the 11th-century historian of the Abbey of Monte Cassino, a monk of Monte Cassino named Monecaus served as provost in a "cell" dedicated to Saint James in the Tremiti Islands during the abbacy of Bertharius. Leo reports that in his day many charters from the time of Monecaus were still in the archives of Monte Cassino. For some reason, Leo later erased this information from his chronicle.
