Vodárenská věž Letná was reconstructed between 2016 and 2018 according to the design of the Petr Hájek architects studio. Currently, the building includes a gallery, a book booth, which includes a children's corner with toys and interactive books from Albi, and a multifunctional social hall. As part of a visit to the tower, it is possible to visit the observation gallery with a periscope. Regular lectures, concerts and other events for children and adults are held here.
