The spillway was built in 1955 with the aim of diverting water from Ribeira das Naves to Lagoa Comprida. It is a part of a hydro-electric dam system of Serra da Estrela.[2] The conical spillway was little-known until photos of the hole went viral in 2016.[3][4][5][6] Over the last 60 years moss and foliage has grown onto the mouth of the funnel, creating an eye-catching sight.[7] It has a height of 4.6 meters and has a circumference of 48 meters. The tunnel that collects the water is 1,519 meters long.[8]
