Segovia Aqueduct

The Aqueduct of Segovia strides straight into the old town like a Roman argument that never ended: raised around the late 1st or early 2nd century AD from granite blocks laid without a drop of mortar, its double tier of 167 arches reaches 28.5 metres above Plaza del Azoguejo and once carried water some 16 kilometres from the Rio Frio into the city. It is among the best-preserved Roman aqueduct bridges anywhere, and UNESCO inscribed it in 1985 together with the old town it serves - a hill of golden stone crowned by a late-Gothic cathedral and the Alcazar, the ship's-prow castle riding the ridge where two rivers meet. The genius is all in the joints: gravity and precision alone hold the arcade up, and standing beneath the tallest arches, watching the stones balance, remains one of Europe's great engineering encounters.

History

With its dedication inscription lost, the aqueduct's date long remained uncertain; at the end of the 20th century Géza Alföldy read the text from the holes that held its missing bronze letters and concluded that Domitian, emperor from 81 to 96, ordered it, probably completed in 98, but evidence published in 2016 points to a slightly later date, after 112, under Trajan or early in Hadrian's reign. It carried water from mountain springs to the city's fountains, baths and houses in an area settled by the Arevaci before the Roman conquest, and it stayed in use until 1973; its elevated arcade of 167 arches is one of the best-preserved Roman aqueduct bridges, and with the old town it became a World Heritage Site in 1985 (Wikipedia, Aqueduct of Segovia).

Highlights

• The Azoguejo arches - the double arcade at its full 28-metre height.
• The dry granite joints - no mortar, only Roman precision, up close.
• The Alcazar - the ship's-prow castle at the old town's far end.
• The cathedral and lanes - the golden Gothic hill the aqueduct feeds.

When to go

Spring and autumn give the kindest light and temperatures; summer afternoons bake the plaza. Come early or stay past dusk, when the day-trip crowds thin and the arches are floodlit.

Before you go

Madrid day-trippers flood the square by late morning - the monument is free and always open, so beat them at breakfast. The climb to the viewpoint steps beside the arcade is short but steep. Segovia deserves an overnight: the aqueduct, Alcazar and roast-suckling traditions are one town ticket.

Nearby
