Spain's Segovia Segovia was built in the Roman period of 80 AD and is the best preserved in countless ancient cities in Spain. The Roman waterway was one of the most important projects of the Roman era. The purpose of the project was to introduce water from the Azerbai River into the city. The 20,400 stones in the entire waterway were not plastered or cemented, but the entire structure was balanced and stable. The highest point of the waterway is located at the Assago Hall, which is 28.10 meters high and contains 167 arches. There is no paste stuck, but it has not fallen down. This can only be said to be a miracle created by mankind. It is a world that does not understand slag, but it is worth seeing. It is indeed majestic. Segovia Cathedral, the cover of the Spanish version of Lonely Planet, is a very visible building. Alcazar Castle, the prototype of Disney Castle. However, reality is not a fairy tale.
