At-Tawheed Mosque is a mosque in York, Pennsylvania, serving a growing Muslim community through congregational worship and community gathering. Its development has progressed from a basement space in a small apartment building to a storefront location acquired in December 2000 that could accommodate up to 100 worshipers, and later to the purchase of two buildings totaling 14,000 square feet in December 2009. The mosque’s history reflects a sustained effort to create and develop space that supports worship, continuity, and the evolving needs of its congregation, with ongoing fundraising contributing to its continued growth.
