Trencadís is a unique Spanish mosaic technique that originated with Antoni Gaudí. Its distinctive feature lies in the use of broken glass and tile shards, which makes each work one-of-a-kind and full of life. The history of trencadís begins with the Catalan Renaissance but it was Gaudí’s works that made this style internationally renowned.
The History of Trencadís
Trencadís emerged in Catalonia as an economical way to create intricate mosaic patterns. Using shards allowed for the creation of rich and vibrant compositions from affordable materials, which was especially relevant at the end of the 19th century when the Catalan Renaissance was flourishing. Local artisans sought new ways to decorate streets and public buildings.

Antoni Gaudí adapted this technique for his unique projects. He used trencadís not only as an economical method to adorn buildings and sculptures but also as a means of expressing his individuality and creative freedom. Inspiration came from Catalan masters like Joan Borras and Miguel Pakes, who decorated streets and public spaces with trencadís.
Gaudí began using this technique in the mid-1890s. His first significant use of trencadís was on the façade of Casa Batlló, where he used colorful shards to create complex patterns and decorative elements.
Examples of Gaudí’s Work
One of the most famous examples of trencadís is Park Güell in Barcelona. Architectural elements and sculptures in this park are covered with bright multicolored shards, creating an impressive mosaic envelope.
In Sagrada Familia, Gaudí applied trencadís to decorate domes and interior walls. Shards of glass and tiles laid chaotically create a unique effect of light and color.
Another striking example is Colonia Güell — the house-museum of Gaudí. Here, trencadís is used to adorn facades, balconies, and interiors, creating a unique atmospheric space.
Trencadís Technique
The creation of trencadís starts with material preparation: glass and tiles are broken into small shards of various shapes. These fragments are then laid on the prepared surface in a chaotic order to create a pattern or an abstract design.

A key aspect of trencadís is creative freedom: each artist can interpret this technique uniquely, making every work unique and irreplaceable. An example of such freedom is the works of contemporary Catalan master Joan Borras, who uses trencadís to create abstract compositions.
Modern Application of Trencadís
Trencadís remains a popular style in modern mosaic culture. Artists experiment with new materials and techniques, combining traditional methods with innovative approaches.
The advent of AI technologies has made creating trencadís more accessible to a broader audience. Image generation programs can interpret this style, offering new inspiring ideas and patterns.
For instance, artificial intelligence can suggest various color and form distributions for creating unique trencadís patterns. This allows artists to quickly experiment with different solutions before working on the mosaic by hand.
The Impact of Trencadís on Modern Artificial Intelligence
Trencadís has become a subject of interest for artificial intelligence and machine learning. Developers use algorithms to create digital models of mosaic patterns that can be used in various projects.
Programmers also develop specialized applications for creating trencadís patterns. These programs allow users to easily create unique mosaic compositions using algorithms and basic principles of Gaudí’s style.
