The decorations of the Masjid of Katara were designed by a team of restoration specialists from Dolma Palace in Istanbul. The mosque features an outer surface garnished with turquoise and purple mosaic, and a wonderful interior design that adds even more glamour. The interior and exterior architectural designs, together with the minaret, the dome, and the prayer niche (mihrab) are all inspired by several famous mosques found in various cities and capitals of the Muslim world. In addition to these notable aspects, the masjid abounds with artistic handicrafts, such as ornaments, inscriptions, and mosaic tiles.
