the Tablets (providing a unique record of business transactions) were discovered there. An aqueduct provided water to the public baths, to more than 25 street fountains, and to many private houses and businesses. The aqueduct was a branch of the great Serino Aqueduct built to serve the other large towns in the Bay of Naples region and the important naval base at Misenum. The castellum aquae is well preserved and includes many details of the distribution network and its controls. Shops and workshops There were at least 31 bakeries in the town, each with wood-burning ovens, millstones and a sales counter. The Modestus bakery, or House of the Oven, was the largest in the city and Sotericus's bakery, also among the largest, preserves the room for kneading bread.

In the thermopolium of Asellina, with three sales counters and a lararium with depictions of Mercury and Bacchus, numerous furnishings have been found, both in bronze and terracotta, as well as 683 sesterces; the external façade bears a representation of jugs and funnels and an electoral inscription referring to Asellina, probably the owner of the inn. Wool processing was well developed with 13 workshops that worked the raw material, seven that did the spinning, nine the dyeing, and 18 the washing: the Building of Eumachia, from the name of the priestess who built it, was the wool market, or the seat of the fullers guild; construction took place after 62 and was entirely in brickwork. Inside it has numerous niches in which statues were housed, mostly concerning the imperial family, a colonnade, and near the entrance, there was a jar in which urine was collected for use as a detergent for clothes. The fullonica of Stephanus, named after the owner or manager, was originally a house that was transformed into a workshop for the processing of fabrics: on the lower floor the working and washing activities took place, carried out in large tanks with water, soda and urine while on
