If you find you can visit this place well worth it. Costs just a few euros entrance fee and you get to watch a 3D film about the 300 Spartans and their battles. Has a small gift shop and cafe and you take to see a few monuments.
Awesome monument here to honor the 300. There are various statues and markers to the heroes. We stopped on a bus tour as a photo op.
I visited Thermopylae in the Autumn 2017, following on from Marathon, and sadly the weather was not good. I was able to get refreshments from the Historical Information Centre, and enjoyed the interaction consoles and 3D film. However, apart from some direction signs, I really…
We stopped here on the drive from Athens to Meteora to see the monument but never saw a center or museum nor any signs.
The museum is very different from what you have thought... It's full of technology experience history moments. They use technology to explain the great battle of Thermopylae! It's at the place where the battle happened... Must visit!
