The Conimbriga aqueduct starts at Alcabideque where the original collecting basin of the spring water is still used as the local village pond. Next to the pond are the impressive ruins of a castellum which acted as a cleaning basin. After 3,5 km the water entered to the town of Conimbriga partly carried by a substructure and ending in a castellum aquae of complex structure, the actual purpose of which is still unclear (cleaning tank and / or basin to slow down the speed of the flowing water ?) After passing this structure the water was brought to the southern bath house and to the forum of Conimbriga.
