One clue is "wave that can't be ridden" and the answer is clearly "sine".
But then intersecting that is a clue "locale of a noted 16th century christian council". And I was thinking "worms", which doesn't fit because sine has and N and not an M.
But then, after like 15 minutes of staring at it, I realized it says LOCALE and not LOCATION.
Rhine is the answer.
