Big yes! Surprised I'm the first to review this, seeing that it's potentially inscribed soon. At first it seems like a generic museum with a mount, but it's actually one of the most important places in history, having been settled for almost 4,000 years including by Hittites, Greeks, Romans, and many more. The amount of variety this culture went through is astounding. The museum isn't very big and not spectacular but gives you a good idea about that. I'm also happy they haven't shifted all the goodies to a museum in Ankara.

Speaking of, it's an hour away from the outskirts of Ankara (add A LOT more time if you are still going through that traffic-laden capital) in a small farming village. It's a nice village though, not the one that has sheep herds and cow dung all over the place. If you are coming from the West or stayed on the D road you would hit the outdoor site first. The small roads coming from the East were perfectly fine, only very few potholes and the one that goes directly south from the site to the D road was almost worst. It's free by the way so if you are really tight on the budget just see the antique city ;)

The entrance to the museum is cheap though, less than a Euro, and gives you access to the museum and the tumulus across the street. The MM tumulus isn't much to look at, containing a strong wooden structure you can peek at from a fence. All the contents has been moved to the museum already. The caretaker also told me where the actual antique city is which of course I knew from the map.

I drove there afterwards and do follow the signs because Google map wants to take you down a diry road. Seems they have added a nice gravel road that takes you to a makeshift parking area from where you can take a round trip on foot to see the remains. While it's only a gate and walls, the boards explain well what you see and its satisfying enough. I suggest you see the museum first though else you may be disappointed by it.
