According to historical sources, the castrum Andoræ was a settlement from Roman times, and, during the Medieval period, it moved from its original position along the floodplains of the Merula river to the hillside of Castello. In 1252 the feud of Andora was sold to the Republic of Genoa who promoted the area to podesteria. During this period, olive cultivation and fishing developed, as well as the opening of the first shipyards. In 1815 Andora was incorporated into the Kingdom of Sardinia, as established by the Congress of Vienna, then subsequently into the Kingdom of Italy in 1861. From 1859 to 1926 the area was included in the III district of the Circondario di Albenga which was part of the Province of Genoa; in 1927, with the suppression of the districts, it passed on, for a few months into the Circondario di Savona and then, finally, into the newly created Province of Savona.

The port of Marina di Andora, is managed by the Azienda Comunale Multiservizi (an instrumental organisation in the Andora City Council) and is very strategically positioned, as it is very close to the centre with a number of shops, restaurants, grocers, pizzerias, bars and cafes. The port can accommodate vessels and pleasure boats of up to eighteen metres, both sail and motor. For transit, approximately forty places are available. The new part of the port is protected by an outer breakwater and a new inner breakwater, which give shape to a new dock protecting the four floating piers within. The older part has, instead, 8 piers.
