Provença–Diagonal station

Provença (Catalan pronunciation:) and Diagonal (Catalan pronunciation:) are two connected rapid transit stations that form a major transport hub in Barcelona's Eixample district. Provença is served by the FGC-operated Line 6 and Line 7 of the Barcelona Metro and the suburban rail lines S1 and S2 of the Barcelona-Vallès Line. Diagonal is an important interchange station of the TMB-operated Barcelona Metro network, served by Line 3 and Line 5.

The underground station complex spans beneath several major streets, including Rambla de Catalunya, Passeig de Gràcia and Carrer de Balmes. These streets intersect both Avinguda Diagonal and Carrer de Provença, after which the stations are named.

Diagonal was the second most used station of the TMB-operated Barcelona Metro lines in 2024, with over 16 million passengers.
