Heidelberg is a city located in the Rhein-Neckar valley in southern Germnay. This is a city that has an American military occupation. Heidelberg American Highschool is the military high school located on Mark-Twain village in the city center, the mascot is the lion, and the school colors are navy blue and gold. Is known to have major rivalries with Wiesbaden and Rammstein. No one else matters, really.

In the year 2011 Mannheim High School was shut down, with most kids moving to Heidelberg. After the year 2013 Heidelberg is set to close, forcing many of the students to move up to Wiesbaden.

Heidelberg is home to the oldest university in Germany, along with the Heidelberg Schloss. Heidelberg boasts a tradition at least 50 years old, 3 times every summer 'Arches' occurs. It is a party that happens every time the castle is illuminated and fireworks are set off. 'Arches' takes place on the terrace of the gardens to the castle, and nearly all Highschool students have attended. This party was invented by Heidelberg students and is a beautiful thing really, I get so trashed every time.

Heidelberg is also known for its domination in football and basketball, it remains one of the toughest schools to beat even in its last year with its lowest population. Heidelberg has won Europeans in football and basketball at least 25 times since its founding over 60 years ago.
