Plaça de Catalunya, or “Catalonia Square” is widely considered the central square of Barcelona. With Raval and the Gothic quarter to the south and 19th century Eixample district to the north, the square sits at the border where the old and new city meet. Leading into Eixample is the famous boulevard, Passeig de Gràcia, along which you will find some of the most opulent homes and shops in all of Spain.
