Taggia borders the following municipalities: Badalucco, Castellaro, Ceriana, Dolcedo, Pietrabruna, Riva Ligure, and Sanremo.

[3] The town is divided into three parts: Taggia proper, located in the Valle Argentina in the immediate outback, it can be considered the proper centre of the city; Arma, a sea resort; and Levà, including the industrial area, placed between the other centres.

The town can be found at approximately ten miles (16 km) from the city of Imperia.

After the fall of the Western Roman Empire, the old centre was damaged by the invasion of Rotharis's Lombards and then by a landslide in 690.

In 1273 it became an autonomous commune, later receiving a podestà named in Genoa, under which it remained until its disappearing in the Napoleonic Wars.
