356 Liguria is a very large main-belt asteroid that was discovered by Auguste Charlois on January 21, 1893, in Nice. It is one of seven of Charlois's discoveries that was expressly named by the Astromomisches Rechen-Institut (Astronomical Calculation Institute), and was named for the Italian region.[3]
13-cm radar observations of this asteroid from the Arecibo Observatory between 1980 and 1985 were used to produce a diameter estimate of 155 km.[4]
