Lucentum (Ancient Greek: Λούκεντον, Loúkenton),[1] called Lucentia by Pomponius Mela,[2] is the Roman predecessor of the city of Alicante, Spain.

The town was refounded as Lucentum (from Latin lucere, referring to the same geographical feature, the "white promontory")[4] after P. Cornelius Scipio conquered the area in the course of the Second Punic War.

The chief cause of this decline was competition from the neighboring city of Ilici (today's Elche), which had better water and land communications and began to usurp Lucentum's trade.

Among these, a number of cauldrons stand out as well as Iberian ceramics decorated with geometric shapes, birds, and fish, sculptures, jewelry, amulets of Egyptian origin, terracotta ware, and weapons.

In the post-war period, the site (located in a privileged place, with an excellent view of the ancient lagoon and bay) was in danger of disappearing, a victim of real estate speculation.

This resulted in recent construction, directed by the architect Rafael Pérez Jiménez and the archaeologist Manuel Olcina Doménech, which aims at the definitive and irreversible conservation of what remains of the ruins.

The most noticeable features are the remains of the fortifying wall (including the foundations of the pre-Roman defensive towers), the baths, the forum, part of the Muslim necropolis, and a multitude of houses.
