The length and destinations of the “Grand Tour” weren’t fixed and could be subject to changes and variations, depending on personal interests and finances, of course.
In any case, like today, the main Italian destination cities were the same.
Venice, the opulent, Florence, where the Renaissance was born, Rome the Great, but also the (less well-known) ancient and sunny Naples, Pompei and Ercolano, and for those who were willing to go further, Sicily was the place.
For Grand Tourists, it was common to have a portrait drawn, set in stunning views, that they could later show to their family and friends when returning home. They would either have their own personal painter or hire a famous local one.
The prestige of a “Grand Tour” was increased by the large number of artefacts that they could purchase along the way and that they would later display in cabinets and studios, to show to their family and friends and be a memory of that unforgettable experience.
