International holidays such as New Year, Christmas, Epiphany, and in Russia, the Russian Old New Year have historically developed as folk traditions with history, customs, rituals, and symbols of celebration filled with specific spirituality. All these celebrations commonly take place in houses and nature with a festive landscape and a green beauty, a Christmas tree and reservoirs filled with symbolic images of traditional holiday heroes. Since childhood, people have been participating in such dear and memorable events related to the history of family and loved ones. The landscape and architectural space of a solemnly decorated city should take into account the cultural, psychological, and historical part of the positive motivations of residents and visitors. Designers and specialists who creatively designed the city's festive landscape and architectural territory should be able to connect the historical, religious, symbolic, psychological, and social foundations of such a multinational city as Rostov-on-Don. For young people, these holidays represent another opportunity to unite with other participants in understanding the joyful time and the community of people around them.
