Aqueduc romain
MonumentHidden Treasure
One of Provence's major Roman remains, the Meyrargues aqueduct unfurls its thousand-year-old arches in a landscape of garrigue and white limestone - a striking testimony to ancient hydraulic engineering.
History
Standing at the gateway to the Provencal village of Meyrargues, in the Bouches-du-Rhône department, the Roman aqueduct is one of the most eloquent testimonies to the Roman presence in Provence. Its limestone arches, partially preserved, rise out of the Mediterranean vegetation with a majesty that belongs only to the great works of Antiquity. Listed as a historic monument since 1922, it is a masterpiece of Provence's archaeological heritage. What makes this monument truly unique is the combination of its past functionality and its formal beauty. Built to carry water from distant springs to the Roman cities in the region - most likely Aquae Sextiae, the ancient city of Aix-en-Provence - the aqueduct demonstrates a mastery of hydraulic engineering rarely associated with the ancient period. Each arcade and each pillar bears the marks of a millimetre-scale calculation at the service of everyday Roman life. The tour offers both an archaeological and a sensory experience. You walk along the remains, skirting the blond stone walls, while the cicadas and the scent of wild thyme remind you that you are in the heart of authentic Provence. The arches, some of which are several metres high, create an effect of depth and perspective rarely equalled in this type of monument. The site is set in a landscape of limestone garrigue characteristic of the Trévaresse massif and the hills overlooking the Durance valley. This unspoilt natural setting enhances the emotion of the heritage: here, nothing disturbs the dialogue between the ancient stones and the blue Provencal sky. Visitors can easily give free rein to their imagination and mentally reconstruct the flow of water that once animated this titanic architecture. As well as its archaeological interest, the Meyrargues aqueduct is also a great place to stroll and contemplate, accessible to everyone. It will appeal to fans of Roman antiquity as well as hikers looking for a historical anchor for their explorations of Provence.
Architecture
The Meyrargues aqueduct is typical of Roman hydraulic engineering in the High Roman Empire. Its structure is based on a succession of semicircular arches supported by massive pillars made of local limestone, a stone that is abundant and resistant in this region of Provence. This arched system enabled a gentle, constant slope to be maintained - generally of the order of a few millimetres per metre - which was essential for the regular flow of water by natural gravity. At the top of the arches ran the specus, a masonry channel whose inner walls were coated with a particularly water-resistant hydraulic mortar made from lime and crushed tile (fragments of roof tiles and ceramics). This technique, inherited from Mediterranean traditions, ensured that the canal was watertight and prevented seepage. The canal was covered with a light barrel roof or flat slabs to limit evaporation and preserve the quality of the water conveyed. The pillars, some of which remain at significant heights, bear witness to the careful construction of the canal: the stone blocks are cut in a regular pattern, testifying to the skills of the Roman lapicides. The dimensions of the structure, although difficult to reproduce in their entirety, are in keeping with the range of medium-sized regional aqueducts, comparable to those that supplied other towns in the Narbonnaise region. The width of the canal, around 60 to 80 centimetres for a similar height, is consistent with the needs of a medium-sized provincial city.
