North-east

Inside the building a stair was leading a bit higher to a room with some piping and vessels, probably for the water or heating circuit. On the other side of the building was seemingly a more or less identical room. Both were completely dark so I had to use my flashlight. The kids started throwing stuff of the roof, I told them they'd better not do that as they might hit someone or someone's car. It was also attracting attention and I was afraid someone might call the cops.

The oldest had already left, the others ran down the stairs because they wanted to explore the basement. I went down too, but stopping here and there to explore some floors. Not much to see, everything was stripped away. Only bare concrete.

Some junk in front of the elevator doors. No interior left, only bare concrete.

On the second floor I noticed I could go across to the other tower (which I thought was locked and unenterable). I had to climb some heaps of debris, courtesy of a bobcat standing there.

More junk and the way to the second tower.
