   There is controversy about the origin of the name of  Vathis Square.

-Some believe that it took its name from a man with a similar name.

-But in the late of 19th century, it was named as 'Vathia' as described by the writers of this era. 'Vathia'  meant a dent, which gathered and stagnant waters of the stream Kyklovorou​​, coming down from the Polygono (now Marnis Street and its continuation, Karolou Street).
