2. The Great Mosque of Aleppo
One of the oldest mosques in the Syrian city of Aleppo, dating as far back as the 11th century, the Great Mosque of Aleppo was severely damaged during the siege of the city in 2013. The Great Mosque is built around a huge courtyard, famous for its extravagant patterned stone floors. The grand minaret was also destroyed by heavy weapons fire, in what the Syrian National Coalition described as a “crime against human civilization”.
