2Serra de Estrela Mountain, Portugal
Oh, just another lake with a massive hole in it! The Serra de Estrela is the highest mountain range in mainland Portugal, and it’s also home to a hydroelectric system of dams, part of which is the Covão dos Conchs with its giant hole. It may look like a natural sinkhole, but it was actually constructed as a spillway that acts as a water diversion.
