Crest Outside Belfast Castle - 1

This is one of two crests that can be seen in the wall just outside Belfast Castle's entrance. Most likely linked to the Chichester/Donegall family. I emailed the castle for clarification but haven't heard back from them as yet. This is one of two crests that can be seen in the wall just outside Belfast Castle's entrance.
