All the way to the very top. Stopped at The Whispering Gallery.... Fun! A few people up here...heard whispering! Incredible, isn't it? Then onward and upward. I count steps...don't know why...I just do. ( I also count clothes pegs on the line...but that's a whole other story...) Anyway...There were signs telling you how many steps up to the Whispering Gallery... I starting counting...but then just decided to believe them! 257 to the Whispering Gallery 376 to the Stone Gallery...at the base of the Dome. 528 to the Golden Gallery...on top of The Dome. I've done it too, Mum, Dad, Greg! The view was magnificent!
