A Romanesque stone bridge locat­ed in the parish of Andor­ra la Vel­la, on the road lead­ing to Sant Julià de Lòria. It was built in the 12th cen­tu­ry and is the largest and best pre­served of its kind in Andor­ra.

La Mar­gine­da is a 33-metre-long arch span­ning the coun­try’s main riv­er, the Vali­ra. The bridge is 9.2 metres high and 7.8 metres wide on one side and 5.3 metres wide on the oth­er. At its nar­row­est point, the bridge is only 2.5 metres wide.

The bridge is paved with cob­ble­stones, the same as the entire road it con­nects. The same cob­ble­stone rail­ings sur­round the stone bridge.
