This article is the first systematic investigation on the location, layout,design and functions of Fāṭimid gardens. Our study is based onprimary sources and focuses on different elements of the recreational andceremonial functions of gardens. Very little is known about the layout of theroyal Fāṭimid gardens because no garden has survived or beenexcavated so far as we are aware. However, we collected physical insights on thelayout and shape of these Fāṭimid gardens through differentarchaeological excavations in Cairo and outside of Egypt, including our recentdiscoveries and the garden that we found in Darrāsa.
