POTSDAM, or POSTDAM, a town of Germany, in the circle of Upper Saxony, with a palace, belonging to the king of Prussia. It is seated in an island ten miles in circumference, formed by the rivers Sprae and Havel. The palace is very curious, and finely built upon a delightful spot 12 miles west of Berlin. E. Long. 13. 42. N. Lat. 52. 34. Reisbeck in his travels informs us, that the houses in Potsdam are still finer than those of Berlin; but like them they are inhabited only by persons of the lower and middling ranks.
