turn right down New Goulston Street, cross Middlesex Street (which was known as Petticoat Lane until 1830) and go up Gravel Lane almost directly opposite. Follow it as it turns into Stoney Lane and at the end of Stoney Lane turn left along Houndsditch.
Enter the underpass at Exit 2 and emerge at Exit 1. (Note the large red sign on the wall opposite which reads Sir John Cass's Foundation Primary School.) Turn right and walk a short distance into Mitre Square.
