In the churchyard of St Anne’s Church in Limehouse, north-west of the church itself is a tall pyramid.
In the stories of Sax Rohmer this was the entrance to Dr Fu-Manchu’s opium den!
The pyramid was built by Nicholas Hawksmoor who was also the architect of the church itself.
Its purpose is unclear though Hawksmoor often incorporated pyramids in his designs and it might originally to have been intended to be part of the church roof or tower.
It does have an inscription “The Wisdom of Solomon”. This may be because Solomon’s temple features in the mysticism and ritual of Freemasonry and Hawksmoor was an early freemason.
