The dome of a mosque is called qubba in the Arabic language. It is a symbolic representation of the vault of heaven. The interior decoration of a dome often emphasizes this symbolism, using intricate geometric, stellate, or vegetal motifs to create breathtaking patterns meant to awe and inspire.
Some mosque types incorporate multiple domes into their architecture, while others only feature one. In mosques with only a single dome, it is invariably found surmounting the qibla wall, the holiest section of the mosque. The Great Mosque of Kairouan, in Tunisia, has three domes: one atop the minaret, one above the entrance to the prayer hall, and one above the Qibla wall.
Islamic art tends to focus on symmetrical and geometric designs, calligraphy, abstract designs and barely representational foliage patterns.
The mosque is usually decorated with decorative borders, calligraphy examples and decorative doors with calligraphy overhead.
Besides the beautiful dome, theÂ Koski Mehmed Pasha Mosque in Mostar also features other architectural attractions such as the mihrab, which is most important element in any mosque because it indicates the direction of Mecca; and minbar which is located to the right of the mihrab, the niche that indicates the direction of prayer.
