The Basilica of the Most Holy Trinity is a modern, circular church inaugurated in 2007 at the Sanctuary of Fátima to accommodate large crowds. Designed by Greek architect Alexandros Tombazis, it seats approximately 8,633 people, making it one of the largest Catholic churches globally. The structure features a distinctive circular floor plan with a diameter of 125 meters and lacks internal support columns to ensure unobstructed views of the altar. The main entrance is adorned with a bronze gate dedicated to Christ, designed by Portuguese artist Pedro Calapez. Inside, the decorative program incorporates diverse religious artworks, including a large gold-leaf-covered crucifix and ceramic panels by Marko Ivan Rupnik. The building was constructed using limestone from the region, specifically 'branco do mar' and 'azul Valverde'. It is situated at the opposite end of the Prayer Area from the older Basilica of Our Lady of the Rosary. The facility includes multiple smaller chapels in the lower level for private prayer and confession. It serves as a primary venue for international pilgrimages and major liturgical celebrations.
