There are not many places in the world, if there are any, where you can see such an accumulation of different layers of civilization in such a narrow place as on Plovdiv's Main Street.

Through the expressive means of visual communication, based on selection of samples of various inscriptions visible in the urban environment of Plovdiv, the authors of the project will create a cultural route. He will be provided with a web application equipped with an illustrated map and interactive links to each of the objects. With the help of this virtual guide, guests and the citizens of Plovdiv will touch the centuries-old history of the city.

It provokes young people to rediscover the pleasure of handwriting and to learn more about letters as an object of art, to learn about the different ways, tools and ways of writing, as well as to participate in calligraphy workshops. For this purpose, the authors of the project create a methodological manual that will be a practical support for the participants.

The first book in the series "The Great Europeans" is based on the program of the same name, broadcast on Radio Plovdiv and BNR, where journalist Plamen Assenov has been introducing the audience to important figures in European history, politics, science, art, culture and social life for four years. The radio portraits are adapted for the purposes of the publication and are illustrated by the artist Alexander Gyoshev. "Great Europeans" aims to reach the widest possible audience, but seeks contact mostly with young people and the middle generation who are not part of the radio listeners.
