The Queen and her sister Princess Margaret once worshipped at St John’s Church at Letty Green.
This was in the 1930s when the two princesses stayed with their grandparents Lord and lady Strathmore. Their home was Woolmer’s Park where the grounds ran down to the River Lea.
The Victorian church is now up for sale having been converted into a house.
Letty Green hamlet with its former church is to the south of The Cowper Arms at Cole Green on the Lea Valley Walk.
