I usually give ancient sites 5 stars, and while it is interesting, it's been over restored and looks like a modern seating area you'd find in a park. Apart from a few areas they left alone, and they're behind iron gates and inside you see modern office chairs which ruins the small amount of the truly ancient part of the site. It's easy to walk to if you're in Kos, and it's free which is really all that's good about it.

An impressive site of historical importance. You can climb the steps and have a good view over the entire site. There are tunnels to explore underneath too. Good information written in Greek and English. And best of all it was free!

This is about a 5 minute walk from the bus station in Kos Town. Quite quiet when I visited which was good. You can view under the steps too. They probably could have done a much better restoration job as the majority of steps / tiers look like concrete.

A well preserved theatre however being an Odeon it's much smaller than oter ancient theatres. Don't let that stop you exploring this place, the information panels in the restored vaulted passageways do an excellent job of telling the complete story of this structure - I especially liked the reconstruction drawing showing it in its glory.

The Odeum of Kos is definitely worth a visit, especially since it’s free. The site itself is impressive, but what makes it even more interesting are the tunnels underneath. They give you a great insight into how the structure looked and functioned before it started to crumble over time. A short stop, but a fascinating glimpse into the island’s past.

Beautiful place, cool you can go inside as well, right near the city centre but feels very different.

You can feel the history of the Odeon as you walk up to it. It is only small but it is quite impressive. It only takes about half an hour or so to look around and take a few photos, but it's worth it. You don't need tickets to enter, and it is free of charge.

Interesting place with a lot of history. Don't miss out that you can walk inside of the building and read about its history and hidden rooms inside.
