Torre de les Aigües, Water tower and garden in Dreta de l'Eixample, Barcelona, Spain

Torre de les Aigües is a six-story water tower with decorative brick moldings and rounded arch windows throughout its facade. A surrounding garden with a shallow pool provides a gathering space around the structure.

The water tower was designed by architect Josep Oriol Mestres for the El Ensanche y Mejora de Barcelona company, which acquired the plot in 1862. The municipal architect rejected the original 24-metre, 730 m³ project for exceeding the district's 20-metre height limit, but mayor Lluís Rodríguez Téllez signed the permit in May 1867. In 1870 the Associació de Propietaris d'Aigua bought the site and added a floor to raise pressure, replacing the original roof with a terrace.

The tower gave its name to the surrounding garden, the first interior block of the Eixample recovered as public space, opened on 15 May 1987. The architects Carme Ribas and Andreu Arriola designed the pond around the tower, and the iron gates are the work of sculptor Robert Llimós.

The site is located at Roger de Llúria 56 and operates from 10 AM to 9 PM during summer and 10 AM to 7 PM in winter. The grounds are easily walkable with seating available throughout the garden areas.

The tower lost its original crowning cap in 1870, when a floor was added to raise water pressure; a flat terrace replaced it. The garden opened on 15 May 1987 as the Eixample's first interior block converted into public space, covering 1,517 m², with a pool designed by architects Carme Ribas and Andreu Arriola and iron doors by Robert Llimós.
