How is tessellation used in architecture ?

Tiling and tessellation are an important area of mathematics because they can be manipulated for use in art and architecture. One artist in particular, MC Escher, a Dutch artist, incorporated many complex tessellation into his artwork. Tiling and tessellation are used extensively in everyday items, especially in buildings and walls. They are part of an area of mathematics that often appears simple to understand. However, research and investigation show that tiling and tessellation are in fact complex.
