The event, which took place through the streets of the Colònia Güell and culminated at the Crypt, combined popular culture, music, dance, historical reenactment, and technology. It highlighted the Crypt of Colònia Güell as a masterpiece of Catalan modernism and a key heritage site in the Baix Llobregat region.
The commemoration concluded a day dedicated to modernism and Gaudí's legacy. In the morning, the 26th Festa del Modernisme was held, a theatrical reenactment of daily life in the late 19th-century textile colony, with a special tribute to Antoni Gaudí and his supervision of the church's construction as its central theme.
The day included a procession with period authorities, stone bearers, and popular culture groups, which passed through Plaça Joan Güell, Barrau street, Plaça Anselm Clavé, and Reixach street to the Crypt. In Plaça Joan Güell, there were performances by the Gegants de Riudoms, a popular culture group, musicians, the Colònia Güell's dragon and devils' group, and a 'xaranga' band.
At the Crypt, authorities visited the monument's interior before moving to the garden for the institutional ceremony. Speakers included Jordi Bartolomé, mayor of Santa Coloma de Cervelló; Maria Pau, Councillor of Culture; Father Josep Maria Domingo, vicar general of the diocese of Sant Feliu de Llobregat; Joaquim Borràs, Director General of Cultural Heritage of the Generalitat de Catalunya; Lourdes Borrell, Deputy Delegate for Democratic Memory of the Barcelona Provincial Council, and Eva Martínez, president of the Consorci de la Colònia Güell.
Subsequently, the laying of the first stone was reenacted, evoking the start of Gaudí's project. The event continued with a dance performance and concluded with a drone light show by Flock Drone Art.
The commemoration was a public festival, offering an opportunity to rediscover the Colònia Güell as a vibrant heritage site through historical reenactment, processions, giants, music, dance, and the light show.
