Tel Aviv boasts the largest collection of buildings designed in the Bauhaus or International architectural style outside of Germany. In the 1930s, German-Jewish architects who belonged to the Bauhaus school imported the defiantly futuristic style when they emigrated to what was then British-ruled Palestine, and the newly evolving city embraced it. But for a long time Tel Aviv neglected its architectural treasures, and only in recent years started refurbishing the rundown facades. Much of the work has been funded by private citizens -- luxury redevelopment that is also helping to preserve the city's architectural heritage. Our report from Tel Aviv.
