Carvalha Bridge, also known as Old Bridge or Várzea (meadow) Bridge is probably the ex-libris of Sertã. Located on the most pleasant part of the town, it is bordered by walking and leisure areas. It was built during the Philippine rule in the 17th century with the aim of eventually replacing an ancient bridge of Roman origin.
