At the request of Queen Louise in 1797, the choral "Lobe den Herrn, meine Seele" ("Praise the Lord, my soul") was played on the carillon each hour, followed on the half-hour by "Üb' immer Treu' und Redlichkeit" (using the aria melody "Ein Mädchen oder Weibchen" from Mozart's "The Magic Flute"). Previously the pieces were simply alternated as was the custom in Holland. In November 1805, the Russian Tsar Alexander I was invited by King Frederick William III and Queen Louise to meet in the royal crypt to celebrate the consolidation of their alliance against Napoleon. On October 25, 1806, after his victory over the Prussian Army at Jena–Auerstedt, Napoleon marched to Berlin and Potsdam and requested to visit Frederick II's private apartment in the Berlin Palace and the royal crypt in the Garrison Church, respectively. His comment that he would probably not have been there had Frederick II still been alive most likely was not said at the crypt as is so often stated, but, out of respect for Frederick II, Napoleon placed the Garrison Church under his personal protection, while he appropriated both the French Church () and the Church of the Holy Spirit () to stable his cavalry.
