Within about 15 years new privately constructed properties replaced the earlier barracks and public buildings, temples and bath houses were under construction in stone. Piped water began to be supplied. Drains and sewers were laid. On the site of the legionary "principia" an imposing central "forum" was laid out surrounded by colonnades and flanked on three sides by part-timbered ranges of shops. Closing off the south of the forum was the 100m x 40m Basilica. Many fine homes with mosaic floors were built in the town.
