Scottish architects Robert and James dominated British Architecture in the latter half of the 18th century. The key period in their development of the neoclassical Adam style was their Grand Tours of Italy (Robert in the 1750s, James in the 1760s), studying classical architecture and producing and collecting volumes of ink, wash, and watercolor drawings. The drawings reproduced in 110 color plates and additional full-page detail views here are all taken from the collection of 57 volumes of Adam drawings purchased by John Soane and held in the Sir John Soane Museum, London, many of which have never been published before.
