Spain Pont del Diable

Just outside Tarragona, in a pine-filled ravine called the Barranc del Diable, stands the Les Ferreres Aqueduct, also known as the Pont del Diable (“Devil’s Bridge”). It is a surviving stretch of the Roman water system that once carried fresh water from the Francolí River into Tarraco, the Roman capital of Hispania Citerior. Built around the time of Emperor Augustus in the 1st century AD, it helped supply a city that was important enough to act as an administrative hub for much of Roman Spain. Today the aqueduct sits about 3–4 km north of the modern city, and it is included in the Archaeological Ensemble of Tarraco, which has been recognised by UNESCO as a World Heritage Site for the way it shows Roman urban planning, engineering, and imperial ambition.

Architecturally, the aqueduct is Roman engineering showing off. It strides across the ravine on two stacked tiers of arches: 11 big arches on the lower level and 25 slightly slimmer arches on the upper one. The structure reaches roughly 27 metres high and runs a little over 200 metres in length (most descriptions put it in the 217–250 metre range). The builders worked with massive, square-cut local stone blocks, carefully fitted without mortar, which means this thing has stood for nearly two thousand years mostly by gravity and geometry. From the ground you can read the rhythm of the arches as they get burned orange by late sun; from the top you see how practical it all was — at the very top sits the former water channel, now a narrow walkway.

For photography, morning light gives you softer pastel tones and usually fewer visitors in frame, while late afternoon and golden hour pull out the rusty reds in the stone and throw long shadows between the arches. Wide shots from below are great for scale — stand back in the ravine, crouch a little, and let the repeating arches fill the frame like a spine. If you shoot from the side at mid-height, you can play with the aqueduct as a leading line pulling the eye into the distance. Walking on top is fantastic for context shots across the treetops, but the channel is narrow and has minimal protection, so kit should be secure and hands free. People-in-frame shots work well too: a human figure under one of the lower arches instantly tells the viewer how huge the whole thing is.

Getting there is very low drama. From the centre of Tarragona (Plaza Imperial Tàrraco), you can catch city bus line 5 toward “Pont del Diable.” The ride takes about 10–15 minutes, with buses running roughly every half hour; you hop off near the park and follow a short gravel path through the pines to the aqueduct itself. The official address is Barranc del Diable S/N, Tarragona, 43003, but most locals just say “Pont del Diable.” A taxi from town is also straightforward and usually costs on the order of 10–15 euros each way. The park is open 24/7 and access to the aqueduct is free, so it works nicely as a quick side trip from the Roman amphitheatre and circus in the old city, or as a dedicated mini-hike when you want ancient infrastructure without crowds.
