Creighton University Observatory
Creighton University Observatory is located on the Creighton University campus in Omaha, Nebraska, United States. It was the first observatory in Omaha, and the second in Nebraska. It was used primarily for the instruction of students, though the directors did do some research in the observatory. It still stands today on the campus grounds, though there is currently no permitted access.

Observatory built
Father Joseph F. Rigge, S.J. arrived at Creighton in August 1885. Assuming responsibility for the telescope, he noted that the constant movement of rolling the telescope in and out of its storage space did not allow for accurate usage and was even damaging the telescope. He suggested a small shed with a removable roof. Father Dowling, the university president, was able to secure $1200 from Mr. Creighton for building a proper observatory.
