This plan is taken from the Russian book "Ani - a History of the City and its Excavations"
by Nikolai Marr, Leningrad and Moscow, 1934. The plan had previously appeared in the 1910 "Little Guide to Ani"
by Hovep Orbeli, published by the Ani Museum. It is an acceptably accurate plan - however, not every visible ruin site at Ani is marked on it. More recent surveys of Ani exist, but they have not been released to the public.
Sites that are numbered in orange on the plan are listed in the index opposite. These "Marr/Orbeli" identification numbers (often abbreviated to "M.-O." or "M-O", for example "M-O 88") continue to be used by modern archaeologists. Numbers in black refer to individual towers within the city walls - numbers 1 to 95 for the outer walls, 1 to 7 for King Ashot's wall, 1 to 4 for the citadel, 1 to 4 for Kizkale.
Main entry points through the city walls are identified with Roman numerals. I: Gate onto Igadzor valley. II + III: Kars gate, inner and outer walls. IV + V: Lion Gate, outer and inner walls. VI + VII: Chequerboard Gate, outer and inner walls. VIII: Gayladzor postern gate. IX: Gate onto Gayladzor valley. X: Gate of Aruch. XI + XII: postern gates. XIII: Gate of Sargis Cilench. XIV: Dvin Gate. XV: Gate of King Ashot. XVI: Gate onto Tsaghkotsadzor valley.
