Liverpool, Berlin, and Paris haven't got that much in common, but all three do share one exceptional characteristic: each has an airport built in the 1930s that still exists. The buildings are protected for special historical and architectural interest, making them an integral part of the cultural heritage. The airports - Tempelhof in Berlin, Le Bourget in Paris and Speke in Liverpool - are traced from inception to current status. The book is an initiative of L'Europe de l'air, a cultural project that focuses on the aviation architecture of Europe and is supported by the European Commission. Its aim is to create a better appreciation of aeronautical sites in general and a greater understanding of their historical significance. This remarkable book pays tribute to a rich architectural period.
