[1] It is named after John Muir, a famous naturalist and geologist who was born in Dunbar and later emigrated to the United States, where he developed his ideas.
[2][3] Designated on 12 October 1976,[4] the park covers an area of seven hundred and thirteen point five hectares (1,763 acres),[5] stretching along 13 kilometres (8 mi) of coastline from Pfeffer Sands to Dunbar Castle.
[7] A number of rare species have been recorded in the park including American black duck, green heron, greater sandplover and semipalmated sandpiper.
[2] Within the boundaries of John Muir Country Park there are a total of 52 sites of archaeological and historical interest, including ruins, buildings, monuments, wartime defences and shipwrecks.
Long after the advent of peace between Scotland and England, the remains of the castle were in the news again in 1842 when electrically fired demolition charges saw their first practical use - blasting a channel through the rock to serve as the entrance for the new Victoria Harbour.
