For thousands of years these directions, which include north, south, east, and west - the cardinal directions, the directions in which the sun rises and sets on the summer and winter solstices, and the directions of extreme motion of the moon (lunar standstills), have influenced the design and alignment of churches, mosques, temples, cities, and other places of importance throughout the world.
