Shadows of a Forgotten World

I first heard of anti-toilets from an article about urine deflectors in London. Since then I have come across them in Austria  and Prague, and possibly a curious indoor one in Lviv . In my recent short visit to London, I came across this set of anti-toilets.

Two types of forgotten urban sanitation means: Boot Scraper Urine Deflector

A modern take on urine deflectors or "pee bumps" - a special paint that makes urine bounce back. From the article: " When peeing in public in this German city, beware walls that pee back "

I feel pretty confident that this unassuming little bump inside a building in the Pidzamche neighborhood of Lviv is in fact a "pee bump" (urine deflector) to prevent people from peeing in the corner.

Such a solution to urban hygiene has been used for centuries, as, for example, can be seen in ancient Venice. Here pissottas ("pee bumps") were installed as can be seen  here  and here . If one tries to urinate, they will be showered with their own pee. In Victorial London urine deflectors were installed, examples of which can be seen here . More examples from both Venice and London here . These still serve a purpose, though I think most people don't know what they are.

In Vienna and Klosterneuburg the anti-toilets are not deflectors but rather metal barriers that prevent people from standing in corners. Thus they also prevent people from loitering.
