The main goal of this essay is to outline a prospective approach related to the hydromineral and geothermal field of Chaves (NE Portugal). The Verin–Régua–Penacova megastructure, trending NNE-SSW, controls the Chaves basin. The thermal water springs in the Chaves urban area have been well known since Roman times with magnificent Roman Bath buildings. Since 1983, the geothermal power available in Caldas de Chaves in three production wells supports a small heat network. Currently, with a long delay of over 35 years, Chaves will enter the roadmap of European cities benefiting from a geothermal district-heating network. The Roman Baths legacy suggests the design and development in Chaves of a geothermal project for direct, continuous, and sustainable use. This project must be adjusted to the resource and demand to promote the region, Chaves city, and the Thermal Bath and comfort its inhabitants and visitors.
