The Carrasco i Formiguera water tower is part of the city's industrial heritage, which once supplied water to the period stately homes.
The water towers we find scattered throughout the city have become monuments to civil engineering. At the Plaça Setze Jutges, the houses are long gone, but the tower that provided them with subterranean water still sands. During the 19th century, water towers were a common element in suburban communities, which set them apart from the wells and public fountains that provided the lower classes with water. Nestled between the new apartment buildings, this structure has become a piece of industrial archaeology. Its elevated water tank allowed the stored water to flow under pressure, reaching the surrounding houses.
