"The Devils of Loudun" was performed in other European countries, where the reviews were mixed again. The Italian premiere given in Trieste in 1974 was praised. In Lisbon, the performance was met with enthusiastic applause in 1976. In 1979, the Swiss premiere of the opera was given in Geneva by the Stuttgart Opera, and the overall impression of the performance was positive; even though a critic said that the libretto and the music failed to maintain the audience's interest, the high quality of staging and the performers made the presentation a positive experience.
