died at age 93.
My mother and I visited the Guggenheim once when we were living in New Jersey in the early 1970s. According to Wikipedia:
Its unique ramp gallery extends from just under the skylight in the
ceiling in a long, continuous spiral along the outer edges of the
building until it reaches the ground level.
It was only after my mother and I walked up the ramp and reached the elevator at the top of the building that we realized you're supposed to take the elevator up and then walk down the ramp.
Oh, well. At least we got some "culture" that day.
