In Darsena Square, adjacent to the Dogan pier, a monument was erected in honour of the fallen of the sea represented by an imposing anchor. The Navy Day takes place throughout Italy in June and on this occasion a laurel wreath is also placed in Cagliari at the foot of the monument. On this date is as well celebrated the venture of Premuda, when, in June 1918, two armed motorboats, led by corvette captain Luigi Rizzo and ensign Giuseppe Aonzo, sank the Austro-Hungarian enemy fleet, contributing to the success of the First World War.
