The UIA Region II covers the Eastern European countries and the countries of the Middle East. This unique regional body of UIA bridges two continents and hosts a vast mixture of cultures, cities and people along with their architectural and urban history and contemporary presence. The UIA Region II represents a very important sector of the world's history of Architecture and Urbanism.
