The UNESCO should consider strongly the idea of giving protection to this marvelous piece of cultural heritage, in which melt the art styles and histories of both great empires and religions in peace, harmony, and great beauty. This monument is also important simply because it has influenced the development of European, Muslim and Christian buildings and designs. There are several reasons behind the need for this monument to be under the protection of UNESCO. Firstly, the merge of different architectural features makes the cathedral truly “stick out” as a vital monument. An example to this may not only be the particularly specific supports of the massive dome- the pendentives, the intricate and colorful mosaics , but also the wooden minaret and minbars – which show the transition in the cathedral’s purpose during the Turkish empire times, but simultaneously gave it a charm like no other building in the world holds. Secondly, Hagia Sophia is one of the few monuments that on a grand scale have had an influence on the art styles and features of a large majority of constructions- from military to religious. For instance, the monument gave the standard for domes in Muslim architecture- as in the progress “…Muslim architects developed enormous and varied types of domes…” (http://iieng.org/images/proceedings_pdf/E0516006.pdf) – an example for such Muslim construction includes the Umayyad Masjid. Additionally, the church- museum should be protected by the organization because of its historical importance- as it was the main cathedral and mosque during Byzantine and Ottoman rule. Nowadays, this precious building is a museum, giving the public an opportunity to view the history and art of the early Middle Ages. To conclude, I think that the “museum” should be under the protection of UNESCO because of a few reasons- the monument is very unique and “one-of-a-kind”, its architectural and art features are historically important , as well as the sole idea that the cathedral represents the peace between the two dominant world religions and the beauty through the variety.
