Serkan and Doruk loved it, and I once more enjoyed it. We made sure to ask for the special visit to the engine room. If you visit it make sure to ask politely the conscript sailors serving on it (the ship is still on the greek naval list and has a active flag). You can easily reach it form the center of athens by taking the Tram from Syntagma to Trocadero (its takes time but it is the most straight-forward).
Here is a ton of pictures taken by Serkan mainly, with some of mine. The ship is a very open museum, with tons of artefacts and a lot of the areas open to public (though not all)
Battle damage on the secondary turrets from the First Balkan War
The forward turret. A part of its armor has been taken out to permit a view of the interior.
