Albarregas Roman bridge

The Albarregas Roman Bridge is a 1st-century BC stone structure spanning the Albarregas River in Mérida, Spain [1]. Built of granite as part of the ancient Vía de la Plata route, it is a Bien de Interés Cultural and part of UNESCO's Heritage of Mercury [1][2]. Constructed during the reign of Emperor Augustus, it marked the northern entrance to Emerita Augusta and facilitated travel across the peninsula [1][2].
