The Arms of Pembroke College
Pembroke College Cambridge, founded in 1347 by Marie de St Pol, Countess of Pembroke, is the third oldest of the Cambridge colleges, and our coat of arms is likewise steeped in history. The College's coat of arms is formed by halving the coat of arms of the Foundress and her husband, Aymer de Valance and putting the two halves together (they are said to be dimidiated and conjoined.) The arms of the Foundress are on the right, those of Valence on the left.
