I found that the biggest common connection these structures had was religious purpose. They varied architecturally and in their ways of preservation. Some cultures rebuilt the structures altogether, others used periodic repairs as a way to bring the community together. Overall though, the original ideas and architecture has been preserved. Modernization has occurred through improvements such as electricity and making the structures more accessible to the community. Tourism and community access brings in revenue to continue to allow improvements on the structures as well as educate on cultural history. Because of this, some of the religious aspect of the structures has been lost, but not all. There is a balance of modernism and preservation of history.
