Luni is a comune (municipality) in the province of La Spezia, in the easternmost end of the Liguria region of northern Italy.

The village is served by National Highway 1 "Aurelia", crossed at Luni Mare by the A12 motorway and counts a railway station on the Pisa-Genoa line.

[4](41.13.4) The Roman city was established in 177 BC by Publius Aelius, Marcus Aemilius Lepidus, and Gnaeus Sicinius[4](41.13.4)[b] It was a military stronghold for the campaigns against the Ligures.

[11][12] In the mid-10th century it experienced the last period of splendour under count Oberto I, who was lord of the whole Ligurian Mark, and momentarily repulsed the pirate threat.

In 1015 Luna was conquered by the Andalusian emir of Denia, Mujāhid, with his Sardinian ships: When Pisa and Genoa beat back his forces, Luni was left destroyed.

[14] The depredation of the Roman ruins of Luni aroused the concern of the local Cardinal Filippo Calandrini, who urged the Humanist pope Pius II to issue a brief (7 April 1461) forbidding any further dilapidations.

It was of little practical use: When the Palazzo del Commune of Sarzana was constructed in 1471 dressed stone from Luni supplied a considerable part of the building material.

Archeological evidence suggests that the Roman forum had been abandoned as a public space by the end of the sixth century CE, its buildings fell to ruin or were demolished and decorative marbles removed.

Cuntz's investigations[16][full citation needed] seem to lead to the conclusion that an ancient road crossed the Apennines from it, following the line of the modern road (more or less that of the modern railway from Sarzana to Parma), and dividing near Pontremoli, one branch going to Borgotaro, Veleia and Placentia, and the other over the Cisa pass to Forum Novum (Fornovo) and Parma.
