I've seen this a thousand times in old movies.

But then I had an appointment in a venerable Hamburg house.

And what do I see? A paternoster.

It had two openings and moved at breathtaking speed.

There is no button to stop it. Only something like this:

It was much faster than an escalator and I couldn't imagine just getting on it.

But there were no instructions for use either.

I took the stairs.
