In a current satellite map of York (see insert), the location of John Snow's birthplace North Street is marked with a red circle (now the Park Inn York hotel).  The All Saints North Street Church where John Snow was baptized on March 15, 1813 (his day of birth) is marked with a green circle. Two reference points are marked with an orange circle (The Guild Hall) and a yellow circle (the Ouse Bridge).
