East london mosque on whitechapel road accommodates 7,000 worshippers with beautiful geometric patterns and modern minaret design. Impressive contemporary islamic architecture different from traditional ottoman styles.

Brick lane jamme masjid (former synagogue then church, now mosque) shows london's religious evolution through one building. Community centers often host cultural events during ramadan and eid celebrations.

Dress modestly (long sleeves, trousers), remove shoes, call ahead for tour times. Aldgate east or whitechapel tube stations. Much more architecturally significant than just walking brick lane for curry houses.
