What is the oldest operating airport?

Could you possibly enlighten me on the identity of the oldest airport that is still in operation today? I'm quite intrigued to know which aerodrome has stood the test of time and continues to serve travelers around the globe. It would be fascinating to learn about its history, significance, and any notable events that have taken place within its boundaries. I'm sure there's a rich story to be told about this venerable institution of air travel.
