The decision to set up the mosques - categorised as A, B and C, depending on the facilities they would have - followed Bangladesh Prime Minister Sheikh Hasina's visit in June last year to Saudi Arabia, where she met King Salman bin Abdul Aziz Al Saud, the Dhaka Tribune reported.
It cited an unnamed official at the Ministry of Foreign Affairs saying that the model mosque project would be launched soon.
The mosques are to be set up in every district, city corporation and upazila.
They will also be outfitted with cultural centres and cyclone centres. The project aims to provide primary education to more than 150,000 children and conduct digital registrations for the annual Hajj pilgrimage to Mecca.
The Saudi government has also agreed to donate money towards the establishment of a permanent campus for Islamic Arabic University in Keraniganj in Dhaka district, according to the report.
