Another advantage is that it has preserved many of its markets, monuments and arts. The researcher into its history and the history of Islamic architecture will find abundant material for students, as Islamic architecture and arts are represented in what has remained of it from the buildings and the edges since the Islamic conquest in 641 AD to 1878 AD.
