A mechitza (halachik wall) together with an eruv chatzerot (Hebrew: עירוב חצרות), commonly known in English as a community eruv, is a symbolic boundary that allows Jews who observe the religious rules concerning Shabbat to carry certain items outside of their homes that would otherwise be forbidden during Shabbat. An eruv accomplishes this by integrating a number of private and public properties into one larger private domain, thereby avoiding restrictions on carrying objects from the private to the public domain on the Sabbath and holidays.
