paved walkway or patio made of rectangular stones laid in a herringbone pattern

paved walkway or patio made of rectangular stones laid in a herringbone pattern. A thick layer of green moss covers most of the stone surfaces and fills the spaces between them, with some stones showing through. Scattered dry grass blades and debris are also visible on the moss and around the edges of the stones. The overall appearance is somewhat weathered and aged, suggesting the walkway is outdoors and exposed to the elements.
