Segovia, 1885 (CA.). Azoguejo Square. The Segovia Aqueduct is the most important work of Roman civil engineering in Spain. To its historical importance we must add its aesthetic and monumental value, due, fundamentally, to the unforgettable visual impact that its contemplation causes from almost any angle... However, the visible part is still a small section of an entire hydraulic complex. which can be traced almost in its entirety. The archaeological value is obvious, not only of the buried conduit but of the aerial hunt itself. On the other hand, this construction, until not long ago, was in use and its functional characteristic has endured during its almost two millennia of existence, an issue that has had an important weight in its complete survival.
