The desire to learn about buildings, cities and cultural artefacts by journeying to experience them in situ pervades architectural history. It can be seen in the rise of the grand tour in the eighteenth century, subsequent formalised academic study tours, the ascendancy of cultural museums in the nineteenth century, and the institutionalisation of heritage sites and attractions in the twentieth century. More informally, such journeys are pursued in personal and less prescriptive ways through habitual urban strolling and site-seeing.
