This briefing is designed as an introduction to medieval structural carpentry—a topic rarely included in conventional texts and courses on medieval architecture. Because this subject is likely unfamiliar, I will introduce some of the major types of carpentry, investigative tools and approaches, essential terminology, and some general building categories as a preparation and context for a more in-depth consideration of two monuments: the Norman Abbey church of Notre-Dame of Jumièges near Rouen, France, dating to ca. AD 1035–1067 and second, the timber-framed complex of urban guild buildings known as the Lord Leicester (Leycester) Hospital in Warwick, England, dating roughly between 1346 and 1571
