When was the first mosqe crated?

The first mosque is generally considered to be the Quba Mosque, which was established in 622 CE in Medina, Saudi Arabia, shortly after the Prophet Muhammad and his followers migrated from Mecca. Another significant early mosque is the Prophet's Mosque (Masjid al-Nabawi), also in Medina, which was built shortly thereafter. These mosques served as places of worship and community gathering for the early Muslim community.
