The East London Mosque (ELM), situated in the London Borough of Tower Hamlets between Whitechapel and Aldgate, serves Great Britain's largest Muslim community. Combined with the adjoining London Muslim Centre and Maryam Centre, it is one of the largest mosques in Europe, accommodating more than 7,000 worshippers for congregational prayers. In 1986, the mosque was one of the first in the United Kingdom to be allowed to use loudspeakers to broadcast the adhan.
