People passing through central Lewisham will know Europe’s largest Police Station and St Stephen’s Church next door.

They may also know the Quaggy and Ravensbourne rivers meet nearby.

But they may not know that as they pass the church and police station on foot, or on a bus, train or tram, that the Upper Kyd Brook is also nearby.

To find out about this mysterious river, where it starts, flows and ends, take John Causer’s virtual tour of the Upper Kyd Brook – from marshy land in Greenwich near the Shooters Hill Road, through Blackheath and down to central Lewisham.
