Explanation:

The Liberation Square or Tahrir Square is the largest public square in the urban center of Cairo, Egypt. The square was originally called "Midan Ismailia", after the mandate of the viceroy Ismail, who promoted the new design of the urban center of Cairo. After the 1952 Egyptian Revolution, which transformed Egypt from a constitutional monarchy into a republic, the square was renamed "Midan Tahrir" or Liberation Square.

Tahrir Square was one of the main meeting areas during the protests in Egypt in 2011, and the main one in Cairo, with more than 15,000 demonstrators occupying the square on January 25.
