A spokeswoman for the council said the concept behind the arch was "loosely based on the sculptural form of a headscarf, reflecting the many cultural backgrounds that have occupied and sought refuge in and around Brick Lane over the centuries".
Using planning-gain funds paid to the council following the development of Bishops Square and Spitalfields market, the trail is intended to bring more tourism into the area and smarten it up. But locals complain that the focus has been too much on the Bangladeshi community, which makes up a third of the Tower Hamlets population.
At the centre of the trail is a 29 metre high minaret that has been attached to the Brick Lane mosque, a grade II listed building originally built in 1742 as a Huguenot church, then converted into a synagogue and now the Brick Lane jamme masjid [mosque]. Tower Hamlets council says the structure "is not a minaret" but a "large steel art sculpture".
