Elusive

This is the City tower in Stockholm, it eludes me. (This is where the Nobel banquet is held). Twice we have tried to get up the tower to see the view. The first time it was closed. The second time it was open, but my legs were in bad shape that day. 
Today we changed trains in Stockholm and I saw the tower from the platform. But today I did not have the time or inclination to visit the tower. I just wanted to go home.
