What's in a Prague street name

Originally published on X on 29 April 2023.

V Tůních was built around the end of the 17th century.

Until 1870, it was known by a similar name, Tůnní.

A tůň, or tůně, is a ‘circular or oval-shaped freshwater ecosystem located in the floodplains of rivers or streams’.

So I guess we’re dealing with a pond, a pool, a water hole or a swimming hole. And apparently there were once several of these round here (see also: https://whatsinapraguestreetname.com/2024/09/01/prague-2-day-169-na-rybnicku/).

However, a tůň occurs naturally, while a rybník is man-made.
