Organ-music geography
Major cathedrals across Europe maintain serious organ programs — many hosting weekly free recitals. Specific instruments (Cavaillé-Coll in Paris, Schnitger in Hamburg, Bach's preferred organs in Leipzig) draw pilgrims. Below are the cities where regular concerts are easy to attend.
Paris
Paris Saint-Sulpice (the Cavaillé-Coll organ, Sunday 11:30am Mass + 12:00pm recital free). Notre-Dame post-restoration (2024 reopening). Saint-Eustache, Saint-Étienne-du-Mont, La Madeleine — all major French organ tradition. Free Sunday recitals widely available.
Vienna
Vienna Stephansdom (St. Stephen's Cathedral) — Tuesday-Saturday lunchtime recitals (free). Plus Konzerthaus and Musikverein for ticketed concerts. Augustinerkirche organ also notable.
Cologne
Cologne Cathedral (Kölner Dom) — Saturday 8pm "Orgelfeierstunde" tradition, free. Plus regular Saturday-evening organ vespers. Cologne Cathedral organ one of largest in Germany.
Berlin
Berlin Berliner Dom (cathedral) — daily 12:00pm-12:30pm midday organ. Konzerthaus and Philharmonie host major organ recital nights. Plus Marienkirche, Gedächtniskirche.
Leipzig
Bach's church city — Thomaskirche (where Bach was Kapellmeister), Nikolaikirche. Annual Bach Festival (June). Year-round Friday Motet at Thomaskirche includes organ.
Hamburg
Hamburg Saint Jacobi (Schnitger 1693 organ — Bach competed for the organist post here in 1720). Saint Catherine's. Strong North German organ-school tradition.
London
London St Paul's Cathedral organ recitals (Sundays 4:45pm). Westminster Abbey, Westminster Cathedral. Royal Albert Hall organ (largest in UK at 9,997 pipes). Tickets vs free vary.
Strategy
Daily lunchtime recitals (Vienna Stephansdom 30 min) sit-and-listen format. Sunday late-afternoon recitals (Notre-Dame, Saint-Sulpice, St Paul's) traditionally world-class. Weekday evening series tickets €15–30. Bring earplugs — organ at full pitch can damage unprotected ears.
