Three colorful shields can be found in the pavement in front of the Reformation Wall. I’m not entirely sure what the one above represents. I’ve read in a couple of places that it’s the Scottish coat of arms. It certainly looks like it, but why it should be part of the Reformation Wall eludes me.

This one is easier – the Geneva coat of arms (See also: Geneva – Parc des Bastions, Eagle Statue).

This appears to be the Bern coat of arms: the capital of Switzerland.
