A greening structure comprising a plant-cultivatable planting portion on a water-reserving portion and laid on a pavement for forming a greening area. The greening structure further comprises post-shaped members provided substantially consecutively from a portion where an external force loaded on the planting portion is directly received, to the bottom of the water-reserving portion or to the pavement, so that the external force loaded on the planting portion is received on the pavement through the post-shaped members. The greening structure is excellent in the supporting strength and the stability to provide a satisfactory treading feel. The substantially consecutive post-shaped members include: first post-shaped members disposed upward from the bottom of the planting portion; and second post-shaped members disposed downward from the bottom of the planting portion.
