Where is magic square?

Excuse me, but could you please clarify what you mean by "magic square"? Are you referring to a mathematical concept where numbers are arranged in a square grid in such a way that the sum of the numbers in each row, each column, and each of the two main diagonals is the same? If so, then the "magic square" itself is not a physical location, but rather a pattern or arrangement of numbers. Alternatively, if you're asking about a specific game, book, or other media that involves magic squares, you may need to provide more context for me to give an accurate answer. Could you please elaborate on your question?
