Chaves is a town located in the north of Portugal, more precisely in the sub-region of Trás os montes "Behind the Mountains".
The ancient Roman city, also known as Aquae Flaviae, occupies a privileged position on the banks of the Tâmega, famous for its therapeutic thermal waters, and was considered in many ways the gateway to the kingdom of Portugal, due to its proximity to the border between northern Portugal and Spain. This is where its name comes from, which means "keys" in Portuguese, and its emblem, which is represented by two keys and a fort. Despite its peaceful surroundings, this place is still a destination steeped in history, with Roman remains and fortifications dating back to medieval times.
The city has a historic centre, the Praça de Camões and imposing monuments such as the Castle of Chaves and the Roman Bridge (Trajan Bridge).
