Die Nacht der O — Hamburg

The Hamburg Nacht der O, at the Catonium on Saturday 30 January 2027 — the night after the slave-market evening at the same house, so the two make a weekend.

Submissive O's serve dominant gentlemen, whether an O is available only to her own partner, offers herself to others in the spirit of the book, or comes for the atmosphere and to be seen. The Catonium is known across Europe for its generous, elaborately furnished rooms, the Red Hall among them.

Admission is between 8 and 9 pm with no later entry; the evening ends around 2 am and all the standard drinks are included. Anyone attending one of these nights for the first time can take a red wristband as a novice, which marks her as available only to her own gentleman.

The dress code is binding. Gentlemen wear elegant evening dress — at minimum a dark suit with jacket and tie, up to a dinner jacket, tails or a top hat — and emphatically not fetish wear, latex, jeans, trainers, T-shirts, frilled shirts or anything standing in for a tie. The O's dress to be easily accessible, from an O-dress through to complete nudity, and wear a collar.

Couples are 140 euros, single women 40 and single men 130 — indications, to confirm at purchase. Tickets are limited and sold in advance only; there is no box office, and unclaimed tickets resold through the waiting list carry a 10 euro surcharge. The format returns on Saturday 14 August 2027.
