A lot of Eiruvin assumes that people live in houses, which open into a walled courtyards (chatzer), with a few courtyards opening into a walled street (mavoi). An eruv chatzeiros allows carrying from the houses into the courtyard, and a shituf mevo'os allows carrying from the courtyards into the mavoi.
Most contemporary eiruvin mimic a chatzer by building a wall around a big area, with no mavoi in the picture and no need for a shituf mevo'os.
Are any mevo'os left anywhere in the world where Jews live and make eruvei chatzeiros and shitufei mevo'os as described in Eiruvin? Or were there recently (maybe in Arab countries)?
