Tahir Square also known as "Martyr Square", is a major public town square in downtown Cairo, Egypt. The square has been the location and focus for political demonstrations in Cairo, most notably those that led to the 2011 Egyptian revolution and the resignation of President Hosni Mubarak. At the centre of Tahrir Square is a large and busy traffic circle. An obelisk of Ramses II, previously at Tanis, was installed in 2020
