Objets Naturels?

More than likely I've got the grammar wrong on this but what can you expect from merely a French O level? More worrying is my understanding of the concept.

Each year Chatsworth in association with Southeby's  produces an outdoor sculpture display in the gardens of the great Derbyshire palace (only 20 minutes or so from Blacka). It makes for an enjoyable  day out and looks good in a highly managed garden placed carefully in a highly managed landscape. These objets d'art are professionally chosen to provoke discussion and dispute, which is doubtless the aim.

Few exhibits however show that timelessness that we find in unmanaged woodland where natural beauty and natural singularity bring such satisfactions.

The Hoof Fungus, Fomes famentarius, the tree lichens and the Witches Broom show a natural artistry not easily matched by manufactured installations.
