The Aqueduct of Segovia is one of the greatest surviving monuments of Roman engineering — a colossal double-tiered arcade of 167 granite arches soaring 28 metres above the Plaza del Azoguejo in the heart of the Spanish city of Segovia, constructed without a single drop of mortar nearly 2,000 years ago and still standing in magnificent condition. A UNESCO World Heritage site and the symbol of Segovia, this extraordinary hydraulic masterpiece transported water over 15 kilometres from the Sierra de Guadarrama to the Roman city, and its sheer scale and perfection continue to astonish engineers and visitors alike.

Roman Engineering at Its Finest
Built during the reign of Emperor Trajan (or possibly Domitian) in the late 1st or early 2nd century AD, the aqueduct consists of approximately 25,000 granite blocks, each precisely cut and fitted without mortar — the weight and engineering precision of the stones themselves provide the structural integrity. The aqueduct carried water from the Río Frío in the mountains 17 kilometres away, descending at a gradient of just 1% over its entire length — an extraordinary feat of surveying and hydraulic engineering.
The most impressive section is the 813-metre-long arcade in the Plaza del Azoguejo, where the double tier of arches reaches its maximum height of 28.5 metres. The aqueduct continued to supply water to Segovia into the 20th century — a remarkable testament to its construction quality over nearly two millennia.
Aqueduct of Segovia is one of the oldest bridges in the world. It is located in central Spain, in the historic city of Segovia.
Aqueduct of Segovia was scheduled by the Roman scholar Vitruvius (80-15 BC). Its construction took place sometimes in the 2nd half of the 1st Century. Aqueduct of Segovia is part of the 17 km long water route which brought the water from the river Fuenfria into the city.
Similarly like at the other ancient Roman buildings, architects did not use mortar to bind the granite blocks together, but metal hooks only.
Aqueduct of Segovia is 28.5 meters high and 782 m long and in 1985 it was together with other monuments in Segovia added to the UNESCO World Cultural Heritage.
