A very detailed diary, Lambton's account reflects his interests in curiosity cabinets, relics and reliquaries, architecture, statues and monuments, and especially gardens, although Lambton was not much of a connoisseur and rarely gives the name of the artist responsible for any works he describes. The diary does include, however, descriptions of places and monuments, including details of buildings as well as collections within them. Lambton lists the contents of several of the cabinets he saw; this focus on curiosities and decorative arts is typical of seventeenth-century travellers. Lambton made many stops on his journey, and mentions many small towns, but gives the longest descriptions of: Rouen, Saint-Germain-en-Laye (where he meets Queen Henrietta Maria and the future King Charles II), Saint-Cloud, Paris, Fontainebleau, Lyons, Avignon, Nimes, Montpellier, Arles, Marseilles, Genoa, Livorno, Pisa, Lucca, Florence, Fiesole, Pratolino, Siena, Cassino and baths nearby, Orvieto, Bolsena, Montefiascone, and Caprarola.
