On 21 September Pilgrim crowned Gisela queen in Cologne Cathedral, which led to a rapid rapprochement between king and prelate.
[11] In June 1031, Conrad appointed Pilgrim archchancellor for Italy, an honour that remained with the archbishops of Cologne throughout the Middle Ages.
[2] Pilgrim was a reformer and a builder, extending the western suburbs of his city by the foundation of the Romanesque basilica of the Holy Apostles (1022/4), a mint (c. 1027) and a new market.
