At the extreme northern end, visible from both approaches,
high on the central buttress of the shrine a beautiful relief by Alice
Meredith Williams of the Calling of St Andrew announces the theme of duty,
the duty both to serve and to remember.
In niches around the four walls are figures of the
Virtues, Justice and Courage by Alexander Carrick which adorn the wings
at either end of the south façade on Crown Square.
