The mosque roof is an important component of Islamic architecture. It is the pinnacle of the mosque structure, representing the close bond between religion and art. Synonyms for the mosque roof include the ceiling, dome, cupola, minaret, and turret. The ceiling is the upper surface that covers the prayer hall. The dome is the spherical or hemispherical roof, often built on top of the prayer hall. A cupola is a smaller dome that sits atop a roof. The minaret is a tall slender tower that adjoins the mosque, and the turret is a small tower or dome-like structure found on the corners of the mosque. All of these structures make up the grandeur of a mosque roof.
