Real "tourism" only affected in Italy in the second half of the 17th century, with the beginning of the Grand Tour. This was a period in which European aristocrats, many of whom were British, visited parts of Europe; Italy, Greece and other Mediterranean places were amongst the most popular. This was in order to study ancient architecture and the local culture. The Grand Tour was in essence triggered by the book "Voyage to Italy", by Roman Catholic priest Richard Lassels, and published in 1670.
