A lot of events take place every year in Nikis square.
Many neo-classical buildings lie around it, like the town hall to the south, the Ermioneion Hotel to the west, and the National bank of Greece building to the north.
Next to the town hall lies the old church of Saint Nicolas, Kozani's patron, and between them stands the clock tower.
It is the symbol of Kozani and its bells can be heard in most parts of the town centre.
There are some statues in the square, e.g. the statue of Georgios Sakellarios, of Georgios Lassanis and of Bishop Ioakeim.
