How did the Greeks design their buildings?

Architecture is the art of designing and creating buildings. Greek architecture is a very specific and influential type of design, which was based off of the post-and-lintel system. The post-and-lintel system is made up of columns, which are large upright posts, with a roof, or architrave, over the top. This type of architecture began with the Greeks, but has persisted throughout the ages to live on today.
