The Museum of Art, Architecture, and Technology (MAAT) boasts a 2,920-square-meter green roof.

Located in Lisbon, MAAT, opened in 2017, consists of the redevelopment of a thermoelectric power plant built in 1908 (MAAT Central), a contemporary museum building (MAAT Gallery), and a garden that stretches along the Tagus River (MAAT Garden).
