Barcelona holds 4 buildings across 3 architectural styles, a compact collection anchored by Modernism and punctuated by two of the 20th century's most iconic structures: the Barcelona Pavilion by Mies van der Rohe and the Montjuïc Communications Tower by Santiago Calatrava.
The most represented style is Modernist, with 3 buildings. The Barcelona Pavilion — originally built for the 1929 International Exposition, demolished, and meticulously reconstructed in 1986 — remains a pilgrimage site for architects worldwide. Its flowing open plan, chromium columns, and onyx walls defined a new spatial language. Richard Meier's MACBA brought late Modernist clarity to the Raval quarter. Calatrava's tower on Montjuïc — a leaning steel needle — represents the Expressionist-Futurist strand. Barcelona's architecture in the catalogue is not about quantity but about the outsized influence of individual buildings.
