For twenty-five years, Steven LaChance has explored locations across the United States and worldwide where unexplainable events occur. These include homes filled with old memories, roads haunted by tragedy, and sites where the past remains palpable. What began as a single life-changing encounter evolved into a lengthy pursuit involving research, interviews, documentation, and listening to those who confided in him. Architecture of Shadows brings together the insights and lessons that emerged from that work. Instead of retelling old cases, this book examines the deeper patterns behind them. LaChance explores how hauntings take shape, why certain locations hold on to what happened there, and what witnesses experience when they find themselves at the edge of what they don't understand. He looks closely at the connections between people, history, memory, trauma, and the residual effects that can shape a place long after the moment has passed. Throughout these chapters, LaChance considers stories from families, investigators, and ordinary people who encountered events they found difficult to describe. Some of these experiences shifted his approach to his work, while others lingered with him long after he left the locations. Collectively, these stories help reveal the key factors behind hauntings and how they impact those who experience them. This book represents the culmination of twenty-five years of documenting, questioning, and exploring people's shared experiences worldwide. It is Steven LaChance's most personal and thorough work, providing a clear and knowledgeable perspective on his beliefs about hauntings after a lifetime of searching for answers.
