The visit to Barcelona Cathedral offers a complete immersion into one of the great treasures of Catalan Gothic architecture. The itinerary allows visitors to discover the history of the temple, begun in 1298 thanks to contributions from citizens and guilds, and completed in the 19th century with the façade financed by Manuel Girona. The experience includes emblematic spaces such as the Choir, the terraces with privileged views, the cloister with its traditions, and the Chapter House, home to the magnificent Desplà Pietà. Visitors will also explore unique chapels such as those of Saint Mark and Our Lady of Mercy. The experience is further enriched with access to the Casa de la Almoina, home of the Diocesan Museum, where permanent and temporary exhibitions can be visited alongside virtual and augmented reality experiences. Finally, the route includes the Baroque church of Saint Sever, a little-known gem in the Gothic Quarter.
