Can anyone guess the function of the palm frond pole?

We went to the north side of Cyprus today. The coast is VERY hot and humid and we weren't very far from the Turkish border- which prompted lots of jokes. One of the oddest thing things I have seen is this pole with a single dried palm frond stuck in the top. Really was quite curious! At some point it deserves a painting! Open to ideas... it didn't provide any shade, wasn't really decorative... ?
