Landmarks Event- Europe 1, #2 Lion's Mound, Belgium! till Oct 31st!

This is my first puzzle for this event and I greatly enjoyed learning about this landmark and its amazing history. It is a monument that commemorates the Battle of Waterloo and is built on the site where Prince William of Orange is said to have been knocked off his horse after being hit by a musket ball in the shoulder.

To find the entrance to the goodies you have to solve a short riddle. The answer leads to an ITSTOOHARD quiz with prizes and the passcode.

My first letter/digit is infinity turned through 90 degrees, my second and third are the "answer to life, the universe and everything", the fourth letter is the most common letter used in English, the next is the last letter of the English alphabet, my sixth part is an eye, my seventh is the same as my fourth and my final letter is uniform in the NATO phonetic alphabet.
