Islamic art is known for its architecture, featuring grand palaces for caliphs and mosques for prayer. Mosques include elements like minarets, courtyards with ablution fountains, prayer halls oriented towards Mecca's quibla wall, and mihrabs and mimbars. While paintings and sculptures of humans are forbidden, Islamic architecture is beautifully decorated with calligraphy, vegetal designs, geometric patterns, glazed tiles, and arches like the iconic horseshoe arch. Domes are also common architectural elements.
