High Quality Content by WIKIPEDIA articles! The seawall in Vancouver, Canada is a stone wall that was constructed around the perimeter of Stanley Park to prevent the erosion of the park`s foreshore. Colloquially, the term also denotes the pedestrian, bicycle, and roller blading pathway on the seawall, and which has been extended far outside the parameters of Stanley Park. It has become one of the most used features of the park by both locals and tourists. Despite perennial conflicts between pedestrians, cyclists, and inline skaters, park users consider the seawall to be the most important feature of Stanley Park and it is the most used park facility.
