A hamlet situated a little distance from Mosta itself yet making part of the locality. Though in the past this small settlement made part of two other localities, as from 1964 Bidnija came within the precincts of Mosta.

Bidnija is a small rural village which is characterised by large tracts of agricultural land which sprawl around the hamlet. Evidence of the remoteness of this small settlement can be deduced from the fact that it remained deprived of even the most basic amenities for a long time. Suffice it to say that the first electrical supply line came to Bidnija in 1965.

Till 1920 there was not even a church for the spiritual needs of the inhabitants. Therefore this rural community decided to buy a piece of land and, on the design of master mason Salvu Zahra (1874-1960) from Mosta, they erected a church in a period of about two years.

Dedicated to the Holy Family of Nazareth, this church now serves the community in its religious needs. The titular painting is the work of Ganni Vella (1885-1977) while the titular statue of the Holy Family is by the statuary Wistin Camilleri (1885-1979).
