A Modernist Masterpiece: The Church of Atlántida by Engineer Eladio Dieste
The Church of Atlántida, located in Estación Atlántida approximately 45 kilometers from Montevideo, Uruguay, stands as a testament to the innovative spirit and architectural prowess of engineer Eladio Dieste. Inscribed as a UNESCO World Heritage Site in 2021, this modernist church complex showcases Dieste's unique application of exposed and reinforced brick, drawing inspiration from Italian paleo-Christian and medieval religious architecture.
More to come…UNESCO Description of the World Heritage Site
The Church of Atlántida with its belfry and underground baptistery is located in Estación Atlántida, 45 km away from Montevideo. Inspired by Italian paleo-Christian and medieval religious architecture, the modernistic Church complex, inaugurated in 1960, represents a novel utilization of exposed and reinforced brick. Built on rectangular plan of one single hall, the church features distinctive undulating walls supporting a similarly undulating roof, composed of a sequence of reinforced brick Gaussian vaults developed by Eladio Dieste (1917-2000). The cylindrical bell-tower, built in openwork exposed brick masonry, rises from the ground to the right of the main church facade, while the underground baptistery is located on the left side of the parvis, accessible from a triangular prismatic entrance and illuminated via a central oculus. The Church provides an eminent example of the remarkable formal and spatial achievements of modern architecture in Latin America during the second part of the 20th century, embodying the search for social equality with a spare use of resources, meeting structural imperatives to great aesthetic effect.
UNESCO Justification of the World Heritage Site
Criterion (iv): The Church of Atlántida of engineer Eladio Dieste represents the highest spatial and aesthetic expression of a construction and technological innovation – the reinforced brickwork coupled with the mobile formwork – that draws from tradition, whilst reinterpreting and innovating it, and opens up structural and formal opportunities in architecture impossible to conceive and achieve up to that date with traditional masonry. The property embodies the post-war search for a renewed architectural language, expressing a modernity rooted in tradition and in the vernacular in Latin America and worldwide. It also reflects the locale and its people who built it. The church illustrates the confluence of geometry, of the static conception of the building, of the form expressed by the chosen building material.

Evaluating Digital Tool’s Integration for the Preservation of XX century Architectures
A robust, multi-tool digital documentation approach enhances the preservation of twentieth-century architectural landmarks, as demonstrated by a case study on Eladio Dieste's UNESCO-listed Church of Atlántida. The research reveals that while SLAM-based methods show greater deviation, they remain valuable for initial surveys or confined spaces, whereas photogrammetry excels in capturing unreachable features, complementing laser scanning's precision. By integrating these tools and aligning their data sets with scalar fields to trace reliability, the study proposes a replicable workflow that improves data quality and supports sustainable conservation practices.
