I once was at Terra Mitica in Benidorm, Spain. It's very theme heavy, with viking/Norse, Roman, Greek and Egyptian mythology. A great looking park!

Nope
Its only cultures from the mediterranean (Egypt, Greece, Rome, The Islands and Iberia), and the park has lived better days, now half the park is closed (Most of Egypt, the islands and the whole of Iberia) and used as night clubs zones.
The theming was done by fallero artists As the park is from the Valencian Community same as the festivities were this artits come from (I live there), so it was pretty well done.
This guys do things like this normally (work on them during a whole year, and then burn them on the 19th of March, to start again the next day):
