A jeweller's in Almuñécar reopened this week after work was carried out to accommodate a 15th-century water system as well as earthenware pots that were found during renovation work.
Jeweller Manuel Torres said that the work had “taken longer than expected” as he decided to make the discoveries a feature in the shop.
A glass floor allows customers to see the five pots that are thought to have been used for wine-making in the modern era.
According to archaeologists, the water system dates from the 15th century and was designed to supply the town.
Last Wednesday a series of engraved Roman washbasins were also discovered in Almuñécar during excavation work near the Cueva Siete Palacios and are thought to have been part of the town's public baths during Roman times.
