Tallinn is known to be one of the best preserved medieval cities in Northern Europe. This Baltic beauty was once home to merchants from Germany, Denmark and other European countries. The name Tallinn or Tallinna is Estonian and is thought to be derived from Taani-linn(a), meaning 'Danish-town'. Its old town is a bustling place especially during daytime in the season when thousands of cruise tourists flood the inner city during day time. Cobblestone lanes following a 13th century path and iron street lamps, gothic spires and medieval markets, cappuccino and Wi-Fi: The old town has it all.
"Does anyone have an idea what this is?", our Estonian tour guide asked when we arrived. We went on a day trip one hour east from Tallinn towards the Lahemaa National Park and stopped at the coast near the Estonian town of Hara. A beautiful, warm and sunny day at the Baltic Sea. Ahead of us a linear concrete structure reaching far into the sea. The area looked like an abandoned military station and in fact it was. "Something with submarines?", a participant from our group asked. "Right, but what exactly?", our guided replied. Well, I would never have guessed since I never heard of what was coming next.
