There's the iconic, but also surprisingly small, Manneken Pis (translated as Little Man Pee). The 1619 bronze statue also regularly changes costumes (housed in their own separate museum), though he was au naturale on the day I encountered him.
Not too far away, down a small alley and attracting only a fraction of the attention, is Jeanneke Pis - a newer, girl version (because you can never have enough fountains of children peeing?).
This one feels slightly more graphic and less "charming" compared to her brother. Though perhaps it was an important step towards gender equality in urination representation?
While this statue of a dog lifting its leg is "dry", the act is the same.
Meanwhile, while boys, girls, dogs and others can seemingly relieve themselves where they like in Brussels, it will cost you or I 50 Euro cents for the same privilege.
