This work investigates the architectural history and structural evolution of the Church of the Holy Sepulchre in Jerusalem to determine its original form and subsequent modifications. Charles Couasnon, an architect who participated in the mid-twentieth-century restoration of the site, utilizes his technical expertise and direct observation of the building's fabric to challenge previous archaeological assumptions. He presents a rigorous analysis of the site's construction phases, integrating historical accounts with physical evidence found during the restoration process.

Experts recognize this text as a foundational resource for understanding the physical history of one of Christianity's most significant sites. Readers frequently note the technical density of the prose, which provides a specialized perspective on the intersection of archaeology and architectural preservation.
