The district underwent significant modifications and re-developments again in the 19th and 20th centuries, alongside major developments in the urban fabric of modern Cairo to the west. Al-Muski Street, a popular market street today, was created by cutting across the urban fabric of the old city to create a street roughly perpendicular to al-Muizz street (the old Qasaba avenue), running from al-Hussein Square in the east to Midan 'Ataba ('Ataba Square) in modern downtown Cairo to the west. Among other important re-developments was the construction of about two dozen new residential blocs with ground-level shops in the eastern sector of the souq, initiated by the princess Shawikar in the late 1930s, which are now some of the areas most frequented by tourists.
