1 · Position
The casino opened in 1923 within the Copacabana Palace — LHL-H-183 — and closed with the national prohibition of 1946. ⚑ The reading of 28 September 2026 adds what the row did not carry: the licence was granted while the hotel was still being built, President Artur Bernardes moved to revoke it in 1924, and the Guinle family won the case only after a decade — so the room the hotel depended on spent its first ten years in court. After 1946 it became a concert hall in the renovation completed in 1949, which is the other use the space survives in.
2 · Why it is in the Library
The group exists to record what a casino did for the houses attached to it, and this is the clearest case of the reverse: a hotel that outlived the room which paid for it. What the Copacabana Palace became after the tables went is the more interesting half of its history.
3 · ⚑ Candour
The opening year, 1923, was carried in the Library’s own build and I wrote that it was unknown without checking; the correction is recorded here. The date and terms of the Brazilian ban, and what became of the room, remain unestablished.
