The Lutheran congregation which has been at St Anne & St Agnes Church in the City for 47 years is moving to nearby St Mary-at-Hill.
The advantage of St Mary-at-Hill is that there are no Sunday services as present. An Anglican Eucharist is celebrated on 1pm on Wednesday.
In the 1980s Peter Lea-Cox and the Lecosaldi Ensemble based at St Anne & St Agnes staged the Bach Cantata Series at the two churches.
The only Sunday when special arrangements will be needed is Sunday 13 October when there is the annual Fish Harvest Festival at 11am.
This Harvest of the Sea service began when the fish market was down the hill at Billingsgate and currently there is a History of Billingsgate display compiled from the London Metropolitan archives at the church.
