Primitive Wall, Old Fence or Romanesque Wall, are names used to identify old walls of Porto, of which only a small part and a small section survived, reconstructed in the middle of the XX century. For a long time known as the Sueva Wall, it is today identified as a work of Roman origin, from the 3rd century, rebuilt in the 12th century. This fence, with an approximate perimeter of 750 meters and an area that did not reach the 4 hectares, delimited the hill of Pena Ventosa that had its neuralgic center in the Cathedral of the Port. The primitive wall had four gates: Puerta de Vandoma: in front of the current Rua Chã, it was the noblest and wide gate, the only one that allowed the entrance of transport; was demolished in 1855. Gate of St. Sebastian: near the Old House; was demolished in 1819. Porta de Sant'Ana or Arco de Sant'Ana, in the Middle Ages also known as the Portal: in Sant'Ana Street; was demolished in 1821. The gate of Lies, from the 14th century Door of Our Lady of Truths: on the Stairs of Truths; the date of its disappearance is unknown. With the growth of the village, in the fourteenth century, there was a need to build a new belt of walls, commonly known as Fernandina Walls.
