Acueducto de Peña Cortada, Roman aqueduct in Calles and Tuéjar, Spain.

The Peña Cortada Aqueduct is a Roman water conduit running through Tuéjar, Chelva, Calles and Domeño in Valencia province. Its surviving remains measure 28.6 km and combine bridge-type sections, such as the three-arch bridge over the Barranco de la Cueva del Gato (36 m long, over 18 m high), with a channel cut through a near-vertical rock cutting 25 m deep and 50 m long. The masonry uses large squared stones.

The aqueduct's remains run 28.6 km from the river Tuéjar intake weir through Tuéjar, Chelva, Calles and Domeño; archaeologist Miquel R. Martí Maties calculates the full line reached 98.6 km toward Valencia or Sagunto, which would make it the longest Roman aqueduct on the Iberian peninsula. In 2004 it was declared a Bien de Interés Cultural. Seventeenth-century writers Escolano and Marés still saw six arches at the Rambla de Alcotas bridge, while Cavanilles in 1795 found only one standing.

The aqueduct reflects Roman engineering skill and remains part of how locals understand their region's ancient past. Walking along it today, you can see how such structures shaped settlement patterns in these mountains.

A circular hiking trail of approximately 10 kilometers follows the Tuéjar River and passes through the Rambla de Alcotas, allowing you to explore different sections. This route gives you a good sense of how the structure connects across the terrain.

The Cueva del Gato bridge is the best-preserved structure of the whole conduit: 36 m long and over 18 m high, with three arches. The rock cut for the nearby Peña Cortada gorge, about 25 m deep and 50 m long, was probably reused as building stone for this bridge.
