Patarei, an old Estonian fortress and then later a prison at Tallinn.
Here's few pics from my short visit there at 1.10.2016, the last weekend when it was still open for the visitors.
All pics are copyrighted, so for the anykind usage, please ask the permission for that.
Thanks for your time and visit!
