Abstract:
In 1901, Antoni Gaudí was commissioned to restore the liturgical elements of Mallorca Cathedral. Among his contributions was the design of a distinctive sounding board for the main pulpit, composed of three parabolic-looking surfaces. Although declared a Historic Monument, the structure was demolished in 1970, leaving only a sketch by Le Corbusier and a few historic photographs as evidence. Based on this limited documentation, this paper presents a digital and geometrical reconstruction of the sounding board using a methodological approach that combines analytical and descriptive geometry with digital modelling tools. The study focuses on reconstructing the geometric logic behind Gaudí’s design, particularly the parabolic surfaces, through a parabolic fitting method. This process enables a better understanding of the original form and proportions, while recovering a lost element of Gaudí’s architectural legacy through a rigorous and systematic reconstruction effort.
