From the words of Mr. Jones-
"The buildings that you have passed and those that now stretch before you, have a genuine timelessness about them. Built in the 18th Century for the Huguenot silk merchants and master weavers, they had by the mid 19th Century become common lodging houses, offering miserable living conditions to the poverty-stricken and partly criminal populace.
Number 4, on the right, which has a distinctly down-at-heel look about it, does in fact preserve much of its 18th- and 19th-century paintwork and fixtures and fittings. Indeed, so unchanged is its character that recent television adaptations of Great Expectations; Nicholas Nickleby and Oliver Twist, as well as several biographical films on Dickens’s life, have been filmed here."
"Built in 1743 as a Huguenot School and chapel, the building was acquired in 1809 by the London Society – a group of evangelical Christians dedicated to converting Jews to Christianity. In 1819 the building became a Methodist Chapel, remaining so until 1897, when it became the Spitalfields Great Synagogue. In 1975, it was converted into a Mosque."
In other words, Christians, Jews and Muslims have all worshiped in that building.
