Spillway in Portugal looks like portal

Near Guarda, Portugal you will find Covão do Conchos, a surreal looking spillway that is part of the Conchos Dam, which is part of the hydroelectric system of Serra da Estrela and gathers water from Ribeira das Naves.

Built in 1955, the small dam diverts water from Ribeira das Naves to Lagoa comprida dam through a 1519 m (4,984 ft) long tunnel. This spillway is known as a bell-mouth spillway and is designed like an inverted bell where water can enter around the entire perimeter.
