The rapid changes in residential environments that have taken place in recent years did not bypass the historic centres of towns and cities. This is where the greatest challenges lie – how can one create a contemporary and harmonious environment in a historical setting? Finding balance between preserving the defined historical character of the place and proceeding with sustainable development of a modern city or settlement is particularly challenging when considering the objects of the 20th century architecture; they have historical value, but at the same time are also a part of everyday life. When it comes to designing a purpose for the architecture of that period, this is a universal problem. In order to find potential solutions to the issue, the architecture and heritage program “Modernism for the Future” of the project Kaunas 2022 – European Capital of Culture initiates Summer Schools for architecture and heritage students and professionals.
