I found though my reading and other research that most of the structures did seem to focus more on preservation. Some would do annual maintenance , celebrations to pass down traditions, or rebuild the entire structure. Along with restricting  general citizen or tourist usage or not allowing it at all.

Modernization seems to be updating with modern amenities such as electricity, HVAC and toilets, which some have not done to maintain historical integrity. Most of the modernization that has been done is a way for the structure to be turned into a tourist attraction to obtain funds to aid in preservation of the structures.

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. 

My concept map may seem a little messy but I feel that all the subjects correlate with one another. To preserve a structure you must take safety measures such as; security, ropes, certain visiting hours and a no-touch policy. To preserve you must also rebuild and touch up structures and artifacts. To modernize a structure you must have lighting, bathrooms, websites, tour guides and so on. To do all of these things it takes money. Most of these structures charge to visit the site or at least the museum. A lot of these structures host festivities and events to bring in revenue. They are also receiving funding, whether from the government or from other parties. Its a cycle, for example to keep a structure relevant and up to date it takes money, to receive that money you charge for tours.

I did find it interesting that to preserve the sacredness of the Great Mosque of Djenne, non-muslims have been banned since Vogue (in 1996) took risqué photographs inside the building.
