Located in the premises of S.G. Żeleński's historic stained glass studio, this 'living museum' offers the truly unique opportunity of visiting an active stained glass workshop, where you'll witness masters at work, learn the artistic process involved in producing large-scale glass installations, and see some superb designs and examples of finished works from throughout the over hundred-year history of the studio. Known as the 'cradle of Polish stained glass art,' Żeleński opened this studio in 1902 as a place for the best artists of the Młoda Polska/Art Nouveau era to meet and work, including such luminaries as Wyspiański, Mehoffer and Stefan Matejko (nephew of Jan). Many of PL's most outstanding examples of stained glass were created here, and today the studio remains the largest of its kind in the country.

Visiting is only possible with a guide and the approximately 45min tour is offered in English at 12:00 and 15:00; Polish tours are more frequent; buy your ticket online to ensure a visit. Inside you'll see a copy of Wyspiański's famous Apollo window, created in the studio in 2018, and the only copy of Polonia - a never-before-realised large-scale window design by Wyspiański which the studio recently completed. Stained glass workshops with a master (make your own souvenir!) can also be arranged (in Polish, English, German or French); workshops are offered for 2, 3, 6 (over 2 days) or 8 (over 2 days) hours (180/250/800/1100zł). The museum also includes a cafe and gift shop where you can pick up beautiful stained glass pieces created on-site in the workshop. Absolutely worth a visit for fans of the medium, as well as Art Nouveau enthusiasts.

Average visiting time: 45mins.
