If you are referring to Old City Walls, they are not necessary today, but are part of the history of the city.
If you are referring to the Western Wall that Jews pray at, this is necessary because the Western Wall (and the less-used Southern Wall) are retaining walls for the esplanade upon which the Dome of the Rock and Al-Aqsa Mosque sit.
