They don't. That's not what it's like. It's just a big well in the ground.

Second pic is the accurate one. You go up the hill, walk in, then all the way down. Exit from there. It's not surrounded by water.

Weird. Doesn't look like the same place at all.

I've looked up pictures of the palace and the initiation well, but that tower is never in the well pictures.

This map shows what the top of the well looks like.
