The Rynok Square in Lviv is a central square of the city of Lviv, Ukraine. It was planned in the second half of the 14th century, following granting city rights by Polish king Casimir III, who annexed Red Ruthenia. The king ordered Lviv to be moved more to the south, where a new city was built to the plan of a traditional European settlement: a central square surrounded by living quarters and fortifications. Old, Ruthenian Lviv had become a suburb of the new city.

The square is rectangular in shape, with measurements of 142 meters by 129 meters and with two streets radiating out of every corner. In the middle there was a row of houses, with its southern wall made by the Town Hall. However, when in 1825 the tower of the Town Hall burned, all adjacent houses were demolished and a new hall, with a 65-meter tower, was built in 1835 by architects J. Markl and F. Trescher.
