Berlin Cathedral
On 7 April 1465, at Frederick's request, Pope Paul II attributed to "St Erasmus Chapel" a canon-law College named "Stift zu Ehren Unserer Lieben Frauen, des heiligen Kreuzes, St. Petri und Pauli, St. Erasmi und St. Nicolai". This collegiate church became the nucleus of today's Evangelical Supreme Parish and Collegiate Church ("Berliner Dom" (Berlin Cathedral)), adjoining the site of the castle.
