Dimona was one of the development towns created in the 1950s under the leadership of Israel's first Prime Minister, David Ben-Gurion. Dimona itself was conceived in 1953, and settled in 1955, mostly by new immigrants from Northern Africa, who also constructed the city's houses. The emblem of Dimona (as a local council), adopted 2 March 1961, appeared on a stamp issued on 24 March 1965.
When the Israeli nuclear program started later that decade, a location not far from the city was chosen for the Negev Nuclear Research Centre due to its relative isolation in the desert and availability of housing.
In spite of a gradual decrease during the 1980s, the city's population began to grow once again with the beginning of the Russian immigration in the 1990s. Currently, Dimona is the third largest city in the Negev, with the population of 33,900.
On 4 February 2008 an Israeli woman was killed and 38 others injured in the town by a Palestinian suicide bomber (see Dimona bombing)
