This moon gate at the Humble Administrator's Garden in Suzhou, China provides a clear opening to the next part of the garden. The narrowing paved stones and even the direction of the leaning tree on the left point in the same direction. The vertical rocks beyond the gate give us a teaser of what's to come.
Good gardens invite us in with clear entrances and pathways that pull us in. Bends and curves draw us forward and peek our curiosity as to what is beyond. Distant focal points encourage us to venture deeper into the garden. Good garden spaces make us want to go into them.
