Nachlaot is a group of 23 courtyard neighborhoods in central Jerusalem adjacent to the Shuk Mahane Yehuda Market known for its narrow, winding lanes, old style housing, hidden courtyards and many small synagogues. Established in the late 1870s outside the walls of the Old City, which was becoming increasingly overcrowded and unsanitary. Some of the courtyards remain Jewish orthodox while other areas are popular for rental to students and others. In the wake of gentrification projects in the area housing prices have risen steeply.
