The built heritage of Peru has exceptional richness, diversity and magnitude. However, it is also affected by deterioration and abandonment, a situation enhanced seismically by its location in the Pacific Circle of Fire. In this perspective, the importance of the structure in the restoration of monuments appears clearly and within it, the role played by those responsible for researching, thinking and implementing the structural strategy of each work. This research contributes to historically assessing the role played by the civil engineer Jorge Marroquín Paiva (1975-2022).  It has a mixed approach and an exploratory level. Techniques such as semi-structured interviews, documentary analysis and observation were applied. Among its results, it stands out that the participation of Engineer Jorge Marroquín helped to develop a more specialized approach to contemporary structural reinforcements that dialogue with traditional construction techniques, especially due to the challenge related to the high seismicity of the Peruvian territory.
