It is located at one end of the terrace, which serves as the roof of what would be one of the plant's engine rooms. It is about six meters down a vertical staircase embedded in the wall. It is not difficult to access, but it can give a little respect due to the height. The best entrance for dogs is through one of the holes in the old water outlet, which is in front of the power plant building, under the terrace of the engine room.
