The Nasir-ul-Mulk Mosque, or the Pink Mosque, stands in the middle of Shiraz in Iran. Every day, when the sun hits the Mosque, the whole building is flooded with a rainbow of colour. Colours from the stained glass dance across the floor in every shade imaginable, while the walls and ceilings glow with intricately painted colours of their own. The breathtaking Mosque was built from 1876 to 1888 and has been a sight of beauty since then.
