2. There was  a large open area in the settlement, where public ceremonies could be held.
3. Unlike most Harappan sites where writing was primarily found on small objects such as seals, Dholavira revealed large letters of the Harappan script carved on wood, signifying a different medium of writing not found elsewhere.
