An ancient stone dome structure at Tel Ibn Salam, also known as the old Matariya cemeteries, located in the Matariya district of Dakahlia Governorate in the Nile Delta region, near Lake Manzala. The structure shows significant deterioration, with crumbling red brick walls, collapsed sections, and scattered rubble surrounding the base, while the dome itself remains partially intact. This site represents an endangered piece of Islamic funerary architecture in rural Lower Egypt.
