Agreed with some of the others that say if you're short on time, nothing special.
I hired a taxi/tour to take me, and I could have skipped it. But, if you have a free morning, it's a good way to kill time. Supposedly there is a very good pork restaurant off the main square (to the right of the church) but they weren't open when I went.
The fertility temple was interesting, and kind of crazy to see. Also, the church in the smaller square that is no longer in use has a phallus on top instead of a cross!
For me the most interesting part was just seeing the town in action. Neat to walk around and experience a small town.More
