and Leon C. Simon Boulevard. UNO's classes were originally housed in the remaining buildings following the closure of NAS New Orleans at that site. As a nod to campus' time as a Naval base, the oldest lecture buildings completed in 1960, the Liberal Arts Building and the Science Building, are both numbered and laid-out like a ship with Liberal Arts featuring exterior balconies for access to the classrooms as opposed to interior hallways, and both Liberal Arts and Science featuring two central courtyards in each building. UNO's newer chemical-sciences annex is designed like a steam boat and many of the newer lecture buildings on campus have similar shapes to the original science and liberal arts buildings without the interior courtyards due to limited space on the main campus. Throughout the years, additional permanent buildings were built to accommodate a larger student body. These include Milneburg Hall (1969), the University Center (1969), the Earl K. Long Library (1970), the Geology/Psychology Building (1972), the Engineering Building (1987), the Life Sciences Complex (Phase 1: the Computer Center, Phase 2: the Biology Building, and Phase 3: the Mathematics Building; All completed between 1979 and 1984), the Chemical-Sciences Annex (1997), and Kirschman Hall (2004). The College of Engineering building is the tallest building on campus. It has a total of nine floors and is home to the university's Naval Architecture and Marine Engineering (NAME) Program (making it one of very few universities in the United States offering this program) among other engineering programs. The first floor is the largest floor featuring large workshop, labs, lobbies, and study spaces as well as the towing tank for the NAME program. Through the breezeway on the first floor is the home of the Dohse Auditorium. Floors two through nine are all part of one large tower in a straight line and are each not as big as the first floor. Two buildings on campus feature atrium designs as opposed to hallways. Kirschman Hall, the newest lecture building on campus and home of the College of Business Administration, features a large atrium in the center with a few satellite hallways connecting to it. It is considered to be the second largest lecture building on campus (after the engineering building). Furthermore, the University Center building, one of the centers of campus life, has an atrium in the center with dining locations and event spaces on one side and hallways with
