Adorning mosques since ancient times, the qubba, or dome, is an important symbol in Islamic architecture. According to some sources, the Romans adopted the dome from nomadic tribes and it survived as a popular architectural structure that is still in use until today. The styles of qubbas vary in different cultures and religions, though the qubba itself represents “the vault of heaven in the same way as the garden prefigures Paradise,” according to James Dickie, who wrote about the Islamic domes in his book ‘Allah and Eternity: Mosques, Madrasas and Tombs.’ Swipe for a look at some of the most famous domes and roofs around the world, drawn by Turkish artist Ahmet Faruk Yilmaz.
