BLERA (mod. BIEDA), ancient Etruscan town on the Via Clodia, about 32m. N.N.W. of Rome. It is on a long, narrow tongue of rock at the junction of two deep glens. Two ancient bridges both belong to the Via Clodia; many rock-hewn tombs imitate houses, with beams and rafters represented in relief (see Koch, von Mercklin, Weickert, in Romische Mitteilungen 09'5), 161 seq.). There was another Blera in Apulia, on the Via Appia between Venusia and Tarentum.
