Gāomì

Gaomi stands on the plain of eastern Shandong, between the inland hills and the Jiaodong peninsula. Its county town first received earthen walls in 1352. In 1523 the walls were faced with brick, four gates were built and a moat was dug. Willows were planted along the moat in 1580 to strengthen its banks. An earthquake in 1668 brought down much of the wall, which local officials subsequently repaired.
