Two new areas, the Nahala UMenucha neighborhood, and Ramat Beit Shemesh, were built in the 1990s, doubling the size of the city.
Ramat Beit Shemesh ("Beit Shemesh Heights") is an expansion that lies directly adjacent to, and to the south of, the original part of Beit Shemesh, colloquially referred to as "Old Beit Shemesh".
