Where is Mary poppins set?

Answer 1

Mary Poppins is set in 1910, as evidenced by the lyrics of The Life I Lead. This means that it is the Edwardian era, although only just, as King Edward died in 1910 and was succeeded by King George V (who reigned during WWI). The Edwardian era strictly speaking came to an end with the death of King Edward in 1910, although some historians see fit to extend it to include such events as the sinking of the Titanic in 1912, and World War I (1914-1918).

Answer 2

In every instance (book, movie, play) Mary Poppins flies in on the East Wind to become nanny to the Banks children of Number Seventeen Cherry Tree Lane somewhere in London, England.

Answer 3
