The Aqueduct of Segovia is one of the best-preserved Roman civil engineering works in the world, built in a period estimated to be after 112 AD, during the end of Trajan's or Hadrian's rule. Its impressive structure shows the skill of the architects of that time.  

The aqueduct has served to transport water to the city over the centuries and maintained this function until the last third of the 20th century. 

It was declared a Historical Monument on October 11th 1884 and a World Heritage Site on December 6th 1985, highlighting its historical and architectural importance.
