Millions of pilgrims flock to Fatima in Portugal every year. A new church building was needed to accommodate up to 9000 people. The Most Holy Trinity Church was completed in 2007 for use at Sunday mass. The challenge was to create a building that, despite its size, would blend unobtrusively into the historical site, offering the possibility to be used for other cultural or religious purposes too. This title features essays, project descriptions, and photography by Fernando Guerra that brings the project to life.
