Out of the ruins there's life

Went for a lovely walk in the forest today and stumbled accross this, could'nt help but wonder what it used to be once upon a time, leading up to its decay.

Took a picture and when I looked back I just liked it, so thought I would share it.

Looks like it was a building of some kind as there were more foundations scattered around the tree's, Good to see the concrete could not keep life down.
