Aqueduct in Segovia
One of the best preserved Roman aqueducts to our time is located in Segovia to the northwest from Madrid. Despite the initial dating for the first century CE in 2016 some researches (analysing finds from 1998) were added, which point to completion of a building in first decades of second century during the reign of Trajan or Hadrian. Any bronze letters, which could inform us about construction date or constructor’s name haven’t been preserved.
