Spiral ramp of Vatican Museum

梵蒂岡美術館入口--1932年由 Giuseppe Momo 所設計。這不只是旋轉梯，還是交錯式的，一邊往上攀升至美術館，一邊則導引您下降至出口，非常特別；可能會在雜誌媒體上常常看到跟這張類似的照片。
This magnificent spiral ramp, designed by Giuseppe Momo in 1932, transports you from the street level up to the floor of the Museums. The ramp consists of two intertwined spirals; one leads up and another leads down. In the picture on the left you can see that people are entering the Museum on the left. While the right hand side of the ramp (the exit) is empty. (現疏散遊客關係只下不上)
