Abrantes became one of the country's most populous and prosperous towns during the 16th century, when the Tagus River (Rio Tejo) was navigable all the way to the sea. With the coming of the railroad and the development of better roads, the town's commercial importance waned. The breathtaking views of the valley from the top of the castle remain, however, and the historical center and friendly locals have also stayed true
to tradition. A stroll through the narrow cobblestone streets is a perfect way to spend a lazy afternoon.
