Dorna Bridge. Probably nineteenth-century arch-like bridge, with easel board arranged over an arch, with a perfect back, with curve access by uneven ramps. Considered from Roman times with a medieval or just Roman phase, the truth is that it did not exist in 1758, as it appears from the Parish Memories of the parish, which refer to other bridges in the region, either in stonework or in wood, such as the Pedrinha bridge, that of Rodeiro, that of Assureira, that of Barziela, Ponte das Veigas, that of São Brás, or even that of "pau", on the site of Porto de Campelo, and should therefore be of a modern and integrating into Castro Laboreiro's local communications network. Despite the impossibility of definitive integration in a chronological-stylistic period, it is notable the fact that it presents mixed characteristics, typical of Roman bridges, such as access through two curves, and medieval bridges, such as the easel board, with a little steep double ramp, the poorly maintained arch staves and the irregular apparatus.
