It is an old Iranian custom to colour eggs during Nowruz, the Persian New Year.
According to a Farsi report by Tasnim, ahead of spring’s arrival, Tehran has been decorated with giant coloured eggs.
Several visual artists have painted these large eggs and the Municipality of Tehran has put the artworks on display.
It is a way to inject vitality into the society and beautify the urban space for Nowruz.
Here are photos of the giant coloured eggs:
