Long before green roofs became necessity and rooftop farming was trendy in North America, Dipl.-Ing Markus Wittling was planning to elevate an entire vineyard on top of the Wine Museum in Cologne, Germany.  Build in 2002, the sloped green roof spans over the entire museum building of almost 20,000 square feet. It is the first vineyard on a roof, the first sloped rooftop farm and the first and oldest organic urban farm on a roof in the world.

In the middle ages Cologne was the most important wine trading town north of the Alps.  The "Weinmuseum Köln e.V." is honoring this factwith a brand new museum with astonishing and educational exhibits on wine. The green roof displays 40 of the most important grape species from around the world situated onto 720 vine stocks.  The soil layer (growing media) including granular drainage is approximately 27 inches deep and consists of a blend of porous volcano material like Lava rock and Pumice - materials in which grapes simply grow best. 

 This rooftop vineyard is a prime example of the performance of modern green roof technology and is ideal for educational purposes.  If you have a chance to visit Cologne, the Wine Museum is a must on your Green Roof Safari and your effort will be rewarded with amazing wine tasting
