How to get to The Observatory
The Observatory is located on the 4th floor of the Physics Building. Start at the fountain of the science complex and face the 2 domes. Walk to the Arc under the domes and go in the door on the left side. Then go up the stairs to your right and go all the way to the 4th floor. It is okay to open the door at the top of the stairs. Then the observatory door is on your left. A video guide is provided here.
