The border checkpoint in Sarpi (GEO) between Georgia and Turkey is located directly on the shore of the Black Sea, and in its striking style is more border stone than border post. The sculptural building appears like a huge wave with towering spray. The architect Jürgen Mayer H. designed this tower with cantilevered terraces and a flat building with a wave shaped roof in 2010. In addition to customs, the border checkpoint is also a vantage point and contains a cafeteria and a conference hall. Thus, at this point, the connecting elements are emphasized over the demarcating ones.
