From "Along the Road" 1925, a series of essays by Aldous Huxley..
"And when at last one has arrived at San Sepolcro, what is there to be seen? A little town surrounded by walls, set in a broad flat valley between hills; some fine renaissance palaces with pretty balconies of wrought iron; a not very interesting church, and finally, the best picture in the world." Wikipedia Resurrection;
How to top that? Well there was a minor battle in the fifteenth century in the valley between Sansepolcro and Anghiari which was to be commemorated by a painting by Leonardo da Vinci in the Palazzo Vecchio in Florence. This is a famous lost painting, mostly known from preparatory studies. Wikipedia Battle of Anghiari;
Sansepolcro has much more to offer (and the Duomo has some interesting art, despite what Aldous Huxley wrote). It is a prosperous small town with good restaurants and small shops, possibly with too many clothes shops. It is at its best on a warm summer evening when the whole town seems to be out on a "passeggiata" - teenagers strolling up and down the main street - and so are their parents and grandparents.
