The Bridge over the Tua River or Ponte Velha, is located in the parish and town of Mirandela, connecting Rua D. Manuel I, located on the left bank, where the old town is located, and Avenida Nossa Senhora do Amparo, located on the right bank. Its construction probably dates back to the 16th century, having undergone several interventions and reconstructions over time. Another bridge was built in the same place at the beginning of the 15th century, but it was during the reign of D. Manuel I (III Letter to Mirandela, by this king on July 1, 1512), when the construction of the current high-rise building with twenty arches began. In the year 1726 there were two niches in its center, one dedicated to Our Lady of Amparo and another invoking the Lord of the Afflicted, represented on a two-meter cross with Jesus Christ crucified. These would have been dismantled in the middle of the following century, as was the granite railing that existed at the time.

In 1866, general repair work was carried out, covering the first arch on the left bank where there was a staircase leading to the river, leaving it with nineteen arches. This arch was identified as a result of archaeological work carried out in 2007 during the remodelling works on the street.

The bridge remained like this until 1909, when, due to major flooding, four arches near the right bank collapsed. The reconstruction carried out in 1910 replaced the ruined arches with only two larger ones, leaving the bridge with the current seventeen arches visible.

In 2016, the bridge, which is used only for pedestrians, was subject to rehabilitation works, which included paving the pavement with granite stone, as it was originally.

It was classified as a National Monument (MN) in 1910.
