East of the Alexandrowka colony is a large park , the New Garden ( '' Neuer Garten '' ) , which was laid out from 1786 in the English style . The site contains two palaces ; one of them , the Cecilienhof , was where the Potsdam Conference was held in July and August 1945 . The '' Marmorpalais '' ( Marble Palace ) was built in 1789 in Neoclassical style . Nearby is the '' Biosphäre Potsdam '' , a tropical botanical garden
