This book is a guide to the city of Oxford. The origin of this city and its famous university has ancient but interesting and unexpected roots. Three of its oldest and most famous colleges are described from an architectural and historical point of view, as well as the most famous churches in the area. The book also suggests a complete itinerary of the city, which includes not only places of religious and academic interest but also activities and places typical of the city where you can dive, dream and spend the whole day. Oxford was in fact defined by the English writer Matthew Arnold as the city of the 'dreaming spires', referring to its architectural and poetic beauty.
