Postman's Park is three parks combined, bringing together the gardens of St Botolph's Aldersgate, Christ Church Greyfriars and St Leonard, Foster Lane.

Medieval Grade I listed church. This church played a key role in the English Revolution and was the parish church of some of the most decisive Puritans: Oliver Cromwell was married and this is where John Milton was buried.
