They would be forgiven for never wanting to set foot in the place again. But some of the 33 men rescued from the depths of the San José mine in Chile have returned to give thanks for their rescue.
A special mass was held for the men and their families, who had waited faithfully for their return.
Not all the 33 made the emotional trip, but those who did seemed healthy and robust.
Meanwhile, a protest by more than a dozen other miners was going on outside. These men were left out of work when the mine collapsed two months ago and say they have not yet been given their promised severance pay.
They are threatening to set up another camp Hope at the San José mine, this time in the hope that they will be paid their due.
