Els Quatre Gats (Catalan pronunciation: [əls ˈkwatɾə ˈɡats], Catalan for "The Four Cats"), often written Els 4 Gats, was a café in Barcelona (Catalonia) which opened on 12 June 1897. It also operated as a hostel, a cabaret, a pub and a restaurant. Active until 1903, Els Quatre Gats became one of the main centers of Modernisme in Barcelona. The artist Ramon Casas i Carbó largely financed this bar on the ground floor of Casa Martí (1896), a building by the architect Josep Puig i Cadafalch in Carrer Montsió near the center of Barcelona.
