Diagram of one method for constructing a "half-round" classical ("Cretan") labyrinth from the center outwards, in six successive stages. You start with a cross 4 units by 4 units, add four inward-pointing 1 unit by 1 unit corners located 1 unit from the arms of the cross, and then start connecting the line endings with semicircles and further corners. The center point of all the semicircles is shown by a red dot. To see the final result (with some slight enhancements), see File:Cretan-labyrinth-half-round.svg .
