 Many German Jewish architects trained at the Bauhaus, the Modernist school of architecture in Germany, and left Germany during the 1930s.Some, like Arieh Sharon, came to Palestine and adapted the architectural outlook of the Bauhaus and similar schools to the local conditions there, creating what is recognized as the largest concentration of buildings in the International Style in the world.Tel Aviv's White City emerged in the 1930s, and became a UNESCO World Heritage Site in 2003.
