Bono had lived here with Ali for a while in the 80s. He had let make the glass top on top of it. Here he wrote "Promenade", singing about the spiral staircase which let up to their bedroom.
"I'd like to be around in a spiral staircase to the higher ground."
U2 had lived here for about half a year during their recording of "The Unforgettable Fire", which partially took place here. They also recorded their music video for "Pride (In the Name of Love)" here.
Also they played several concerts here.
It's planned to build a big tower with a recording studio on top of it right here next to the river Liffey. It will be called "U2 Tower" and U2 will have their very own recording studio up there.
But now it's suspended for unknown time.
