After the foundation of New Town in Prague in 1348, Charles Square was defined as the centre of its southern part.Marek Lašťovka – Václav Ledvinka a kol., Pražský uličník I.: Encyklopedie názvů pražských veřejných prostranství, Libri, Praha, 1997, pp. 320–322. It was originally called Large Market, New Town Square or the Square of the Upper Town, from the 15th century until 1848 it was known as Cattle Square, and since 1848 it has been called Charles Square (after Charles IV, the founder of New Town).
