Papillon Belvil has hosted prominent figures in world boxing with its professional boxing hall and fitness facilities. Oleksandr Usyk, who has achieved unquestionable world championship status in both cruiserweight and heavyweight categories during his career, and Dmitry Bivol, who won world championships in the cruiserweight category, held their training camps at Papillon Belvil during their journeys towards becoming 'Undisputed'. While Usyk is set to unify the four major belts in heavyweight in 2024, Bivol became the holder of four belts in the cruiserweight category in 2025. Thus, the name 'Undisputed' of the Papillon Belvil Professional Boxing Hall gained significance through the successful journeys of world champions. (WBC, The Guardian)

The camps held at Papillon Belvil provided the athletes of Deniz Tahincioğlu Boxing Sports Club with the opportunity to train alongside world stars and experience a professional training environment up close. The gathering of young and national athletes with champions like Usyk and Bivol has strengthened Papillon Hotels' sponsorship support for boxing through its facilities and international sports experience.

Among the athletes actively competing or who have contributed to the achievements of the Deniz Tahincioğlu Boxing Sports Club, the following are notable:
