Thus, there are lightning rods in the pyramidion, even in its pencil-sharp point. The eight windows at the top will be reglazed and the red aircraft warning lights recaulked. But mostly the work will involve the marble blocks. That's where most of the stone is still good, but it's so damaged that a patch wouldn't hold, so we cut out part of the stone and replace it with a similar piece, pinning it into the stone. Marble doesn't take pressure that well.
Pressure builds on the corners and they break off.
Already, especially on the bottom 40 feet of the shaft, there are a lot of dutchmen in place. The second one is now a swimming club. We had a topographic map and we pulled in on a hot June day to look for stones, and they didn't have a clue what we were doing. Then there is the matter of old stains, some from the dirt in the air, some from copper gutters that were installed over the windows at one time. Even when the gutters were finally removed, the hardware that held them to the building was left and stained the stone even more.
