Carl Eugen traveled to Paris for the first time in 1748 together with his new wife, Elisabeth Friederike von Brandenburg-Bayreuth. Over the course of his life, he visited the city four more times, accompanied by his companion, Franziska von Hohenheim. Their visits always included a busy schedule of sightseeing. Sights, military installations, and especially bookstores were of great interest to Carl Eugen. In the evenings, one would meet at the Palais Royal, the promenade and leisure spot in Paris, or attended the theater.
