困惑的一个单词

“Stadiumon”还是“Stadium on”？有点困惑。
一个表象是这样的，MINOA Kyriakou, the president of Hellenic Olympic Committee, handed the Olympic flame over to Liu Qi, the president of BOCOG, at the Panathenan Stadiumon today after the six-day torch relay in Greece wrapped up.  “at the Panathenan Stadiumon today ”.
Stadium=Stadiumon？ 谁的字典大一点，查一下看看。
