Kaleidoscope of spiral stairs

It's hard to explain, but there is something attractive about the perfect shape of spiral stairs, so sometimes it's impossible to look away. Interestingly, spiral staircases appeared quite late in architecture because of their complex structure. Although the first examples date back to the V century BC, this element of architecture was firmly established only in 113 AD. Spiral stairs give the building a more romantic look. Even Dr. Sigmund Freud did not ignore them with his attention, saying that the ascent and descent of such a staircase resembles (naturally) sexual intercourse. The world is full of spiral stairs, let's take a look at some of them.
