Worth every cent ,i can advise only book as early as you can.I went 9 was almost empty ,so much space, so relaxed.
very happy i went without a guide so I could go at my own pace. so much to see and read about during my time there I actually ran out of time as the day I went it rained all day that was in September
Absolutely stunning views and unforgettable experience. The building itself is unbelievable and beautiful. Very quick to entry and helpful staff
