Al Mafjar roughly translates to 'bomber'. There is a high ground to the north of the village which has long prevented seawater from washing in, but when sea levels rose unexpectedly, the seawater "exploded" and spread around the village, thus giving it the name 'Al Mafjar'.
Geography
Al Mafjar is located on the eastern side of Qatar's northern coast. The line connecting Al Mafjar and Abu Dhalouf serves as a demarcation between the coastal plain areas to the north and the interior plains to the south, the latter area being characterized by a gradual widening to the south of this line.
