"Green and pleasant Land".

And did those feet in ancient time - Wikipedia, the free encyclopedia
Blake lived in London for most of his life, but wrote much of Milton while living in the village of Felpham in Sussex.
Amanda Gilroy argues that the poem is informed by Blake's "evident pleasure" in the Felpham countryside.

The phrase "green and pleasant land" has become a collocation for identifiably English landscape or society.
It appears as a headline, title or sub-title in numerous articles and books.
Sometimes it refers, whether with appreciation, nostalgia or critical analysis, to idyllic or enigmatic aspects of the English countryside.
In other contexts it can suggest the perceived habits and aspirations of rural middle-class life.
Sometimes it is used ironically, e.g. in the Dire Straits song "Iron Hand".
