Amoreiras Water Reservoir in Lisbon, a marvel from 1746 designed to harness water from the Águas Livres Aqueduct. Though its days of operation are over, the reservoir's impressive 7.5-meter depth and the sprawling 18-kilometer Águas Livres Aqueduct offer a glimpse into Lisbon's past water management challenges. Ascend to the rooftop terrace for sweeping views of Lisbon's skyline, and marvel at the magnitude of the aqueduct standing beside the reservoir. Best of all, admission was free on the Sunday we visited, making it a must-see historical site in Lisbon. Don't miss this unique piece of the city's heritage! 🏞️🏛️
