Answer:
Moorish/Muslim, Roman, and Byzantine architecture all share several common features. One of the most notable similarities is the use of arches and domes in their architectural designs. These structures were used to create grand, open spaces and to give buildings a sense of height and grandeur. Additionally, all three architectural styles incorporate elaborate decorative elements, such as intricate patterns, mosaics, and geometric designs, to create visually striking buildings. Another common feature is the use of geometric shapes and symmetry in the layout and design of buildings. Overall, these architectural styles share a focus on creating grand, visually impressive structures that were meant to inspire awe and admiration in their viewers.
