Learnt a lot of history of the country from my friend Mati Remussen. He is a bit of a celebrity among the guides here. You can find his name in Rick Steves’ book!

Check out how sharp the edges on the top are

It is a sauna heated by wood. I understand saunas are big in Estonia.

This is all underground water – and not fed by rivers. Which is why it is so clear and cold.

Because it was a mine, the drop in height is very quick. That building – that was used for prison and mining operations is actually four floors in height. Most if it is underwater!

Very interesting how wind and water has eroded what is left after limestone mining. Almost looks like sharp edges.

This is the original place I wanted to come to. The limestone quarry is stripped off the limestone and this is what remains. During the mining, big Soviet pumps were used to drain out the water. The story goes that when the Soviets retreated the valuable copper in the coils were stolen. The pumps stopped and the underground water soon filled up the hollows. Since this is water coming from the ground, it is very clear and cool.

The famous prison of Murru Vangla. There were three prisons inside that complex. They were built specifically here next to the quarry to keep the prisoners busy.
