Major buildings in Mamluk Tripoli included six congregational mosques (the Mansouri Great Mosque, al-Aattar, Taynal, al-Uwaysiyat, al-Burtasi, and al-Tawbat Mosques). In addition, there were two quarter mosques (Abd al-Wahed and Arghoun Shah), and two mosques that were built on empty land (al-Burtasi and al-Uwaysiyat). Other mosques incorporated earlier structures (churches, khans, and shops). Mamluk Tripoli also included 16 madrasas of which four no longer exist (al-Zurayqiyat, al-Aattar, al-Rifaiyah, and al-Umariyat). Six of the madrasas concentrated around the Grand Mosque. Tripoli also included a Khanqah, many secular buildings, five Khans, three hammams (Turkish baths) that are noted for their cupolas. Hammams were luxuriously decorated and the light streaming down from their domes enhances the inner atmosphere of the place.
