First published in 1912, this volume provides a list of all Romano-British structures in the British Isles known at the time of publication, complete with references to published works on each structure, arranged by county. This volume omits burial sites and circumstantial evidence for occupation, focusing on a wide range of excavated structures ranging from military defences to foundations and pavements. The detailed references for each structure provide a valuable resource for researching the extent of previous excavations on a site, and for recovering information on structures which have since been lost or destroyed. Modern discoveries can also be placed in context with earlier excavations in the same area. The author, Arthur H. Lyell (d. 1925), was a prominent archaeologist specialising in Roman Britain.
