The terraced vineyard (Potsdam)

 garden, vineyard / grape plantation, interesting place

On 10 August 1744, Frederick ordered the bare hillside to be transformed into terraced vineyards. Three wide terraces were created, with convex centres to maximise the sun light (see plan). On the partitions of the supporting walls, the brickwork is pierced by 168 glazed niches. Trellised vines from Portugal, Italy, France, and also from nearby Neuruppin, were planted against the brickwork, while figs grew in the niches. The individual parts of the terrace were further divided by strips of lawn, on which were planted yew trees. Low box hedging surrounded trellised fruit, making a circular ornamental parterre. In the middle of this "wheel", 120 steps (now 132) led downward further dividing the terraces into six. (quote from wikipedia)
