Descending a Spiral Escalator

There aren't many spiral escalators in the world. The video here gives us a panoramic view of traveling down one in Caesar's Palace Forum Shops, in Las Vegas.

Possibly the first spiral escalator appeared in London 1909, but was apparently scraped before completion, according to Tom Hall's blog.

One of the few and most remarkable spiral escalator installations in the world is the one found in Yokohama Minato Mirai, engineered  by the Mitsubishi Electric Corporation which has developed and manufactured successful commercial designs since the 1980s.

Spiral and or curved escalators would seem to offer unique panoramic views of any building that has large open  interior atrium airspaces.
