Memorial gate

We spotted this colourful gate in the farmlands outside Durbanville. There didn't seem to be an obvious reason for its existence (on either side the fence just stretched on for hundreds of metres), and so we guessed it to be a memorial of some sort - there are flowers on the tree and in the pots behind the gate as well. I imagine that someone must have lost their life on this lonely stretch of road - a sad thought, but what a beautiful and unusual way to celebrate the life of a loved one.
