No, it must be something else. The cableway is still exists.
I should have taken a picture. Sorry.
The tower made from concrete (iirc) and looks like two stacked cylinders: the low cylinder had a diameter of ~1m and was ~1.5m high, the top cylinder a diameter of ~2m and ~3.5m high. The top cylinder had a door and there were stairs outside leading straight up to this door.
