Els Quatre Gats Opens in Barcelona's Casa Martí
確定確度 75%Wikipedia[1] states the day outright: "The café opened on 12 June 1897 in the celebrated Casa Martí".
The café that became the meeting room of Catalan modernisme opened on 12 June 1897 in the Casa Martí, a Puig i Cadafalch building in the Gothic Quarter. It lasted only six years in its first run, but in them it hosted Picasso's first solo exhibition and the circle around Rusiñol and Casas - and he drew its menu card.
