The Hagia Sophia (Ayasofya in Turkish), which means Holy Wisdom, is a grand piece of architecture that beautifully defines the Istanbul skyline. According to our tour guide, it was originally an Orthodox church which was turned into a mosque and eventually converted into a museum. It was truly a humbling experience to stand before this ancient wonder and be able to walk along its endless halls and explore its grand chambers.  Inside was generally empty except for a few relics and lighting fixtures, however, the walls and ceilings are covered with a spectacular array of religious artwork. It was fascinating to see Christian and Muslim symbols beautifully complementing each other. I think the world can learn from the walls of Ayasofya on how to coexist harmoniously despite our differences.  Sadly though, recent developments in Turkish politics may eventually lead to reviving this museum back into a mosque. I just hope the people of Istanbul decide to retain this as a symbol of secularism where people from all faiths can enjoy the beauty and wonder of this great human achievement both in construction and architecture.
