roof features an iconic clock tower, which overlooks the Rose Garden. The building houses administrative offices, classrooms, and art studios for the Arts Department of the School of Art and Design. In February 2013 a fire erupted throughout the top floors of the building, destroying much of the interior structure and students work. East Hall is located directly behind Main Hall and faces Grand Walk. Designed by William Windrim, a main feature of the brick building is the large smokestack which served the institute's power generation plant. Within the Hall are a variety of services for students including Career Services, Student Activities, International Student Affairs, and the Pratt Chapel. Located in the lower level of the building is Pratt's continuously operating, privately owned, steam-powered electrical generating plant built originally to serve the power needs of the school. In 1977 the facility was recognized by the American Society of Mechanical Engineers and named a National Mechanical Engineering Landmark. The Student Union, by architect William Tubby, was originally built as the Trade School building but soon after completion was completely remodeled as the Student Union complete with gymnasium and swimming pool. In 1982 the building was renovated again as the new Student Union. All three buildings wrap around an interior courtyard which connects out to the Newman Mall and Library Rose Garden. The centerpiece of the courtyard is a 17th-century Italian marble well-head fountain purchased by the Pratt family in 1900. Other structures include: South Hall, located along Reyerson Walk to the direct south of Main Building, was finished in 1892 by William Tubby and was built as the Pratt High School. When the high school closed near the turn-of-the-century, the building was used for the School of Domestic Arts and Sciences. The building is now home to classrooms, studios, and offices for programs in the Department of Fine Arts, part of the School of Art and Design. Pratt Institute Library, which was opened in 1888 to serve students and the general public as well, became the first free Public Library in Brooklyn. The architect of the building was William Tubby of Brooklyn. The decoration in the building was done by the Tiffany Glass and Decorating Company. The Chemistry, Machinery, and Engineering Buildings are located across from Grand Walk and East Building, which are clustered around the Engineering Quad's lawn and gardens. They were built in phases between 1908 and 1928 and
