ON SWANSCOMBE MARSH

摘要

Swanscombe Marsh is a peninsula pointing north within a loop of the River Thames below Greenhithe. To the south it is bounded by cliffs left after two centuries of chalk quarrying. The flat lands, once marsh grazing and saltings, have been transformed since the beginning of the 19th century by cement and paper industries to the south, by riverside industrial development to the east and by successive waves of landfill including the reclamation of the saltings in the early 20th century. The Channel Tunnel Rail Link emerges from its river crossing in the south of the marsh.
