Lion Battery (The Noon Gun)

"If you’re walking around Cape Town at midday and hear a loud gunshot, don’t be alarmed. Although locals are accustomed to it, visitors are often surprised by the sound of the Noon Gun. The Noon Gun is a cannon that has been fired every day at noon since 1806, making it one of the oldest traditions in Cape Town. The tradition of firing the Noon Gun dates back to the early days of Cape Town when ships in the harbor would use it to set their marine chronometers."
