Can anyone guess what this small hole filled with water, in the center of a fort built in the 1600s on an island just off the coast of Colombia was used for?

Hint #2: there are several small narrow tunnels that shoot out from the hole outwards in different directions

Answer: Small narrow tunnels shot outward and connected to the sea. As boats approached they could tell which direction the boats were coming from by observing the water’s movement in the hole. The local guides called it a sefon, and we made a joke it was a sea-phone, because it was a communication device for the sea. Pretty neat engineering design. There were some good guesses in the replies.

They had koi 🐠 swimming in it as a pond, allowing them to sit around it drinking tea, lulling the subject pleasantly into revealing state secrets over biscuits and scones, right?

Zero idea; yet evaporation rate could be one piece of info derived from standing water and dew points inferred.

I think I’ve been to this fort! Is it the one where right down the hill is another building that was for people with leprosy?

Based on hint 2 I'd say the level would rise when ships enter the bay. But for that, the fort has to be close to a bay. I can also see it being used for waterboarding of some sort. Oh, wait.... No... It's messenger fish. Like pigeons, but the fish. Right?
