In common sense, the basis of architecture is just solid buildings mixed up with bricks, stones and woods. Yet it is true that all forms of architecture do show similar functions, such as as storage, protection and sheltering. Beyond those cold and symmetrical walls, however, lays the exuberant imagination of the artists; architecture has its very own avidities as celebrating humanity, revealing humanistic civilization, or depict spirituality. From ancient clay buildings, to great Renaissance to the modern 21th century; from East Asian bamboo, to Islamic world to the Roman Plaster; during decades of era, architecture stands there, revealing the most beautiful human artistry.
