The Tower of Jesus, the highest spire of Barcelona's Sagrada Família, is scheduled for completion this month [2].
This milestone coincides with the centenary of Antoni Gaudí's death on June 10, 1926 [4]. The completion of the tower marks a critical step toward the final realization of the architect's vision for the basilica, which has remained unfinished for a century.
Records indicate that Gaudí employed a specific technique known as trencadís, a mosaic made of broken ceramic and glass tiles, on the highest points of the towers [1]. He reserved the most expensive materials for these pinnacles [3]. This choice was not merely aesthetic; Gaudí intended the bright colors to be visible from the sea [1].
"El color es expresión de vida," Gaudí said [1]. By placing high-cost ceramics at the peak, he ensured that the spires would serve as a visual beacon for ships arriving at the coast [1].
The Tower of Jesus reaches a height of 172 meters [4]. While this tower is slated for completion in 2026 [2], the entire project is not yet finished. The final phase of construction, known as "La Gloria," is aimed for completion in 2036 [3].
The use of trencadís allowed Gaudí to cover curved surfaces with vibrant, weather-resistant materials. This approach integrated his fascination with nature and geometry into the structural heights of the city's skyline. The current construction phase focuses on finalizing these details to match the original specifications left by the architect.
“"El color es expresión de vida."”
The completion of the Tower of Jesus in 2026 represents the intersection of early 20th-century artistic intent and modern engineering. By finalizing the tallest spire during the centenary of Gaudí's death, the project transitions from a long-term construction site into a nearly completed architectural monument, though the decade-long gap until the 2036 completion of 'La Gloria' suggests that the final symbolic and structural elements of the basilica still require significant resources.
