Forgotten garden

It's the kind of place no one would think of looking. Walking past it on the street, slightly sunken from the level of the road, it is barely worth turning one's eyes to, a mess of tangled pointless greenery, sandwiched between the two walls of the neighbouring houses. It must have been useful to someone in days gone by; the wooden ladder wouldn't have been built if the garden was never going to be used. Someone must have had high hopes for this patch of earth in past times. There's a grapevine plant growing unchecked at the top, while the whole patch is practically overtaken by a wild olive tree. The weeds are thriving, maintaining a no man's land of the site.
