The reason I decided to place the chapel in the circle is because there are currently not a lot of buildings in the circle, and because of the importance of the chapel to the campus I wanted it to stand out in a formal space and not be hidden in between other buildings.  I also chose this space because it is close to all the major parts of the campus so whether you are in the campus center or your dorm, you will not have to walk from one side of the campus to the other to access the chapel.  Lastly the reason I placed it in the part of the circle I did is so it can follow the direction of the sun and runs parallel with the green house.
