University of Nevada-Las Vegas (UNLV) is a public, coeducational university located in the Las Vegas suburb of Paradise, Nevada, USA. The 337-acre (136 ha) campus is located approximately 1.5 mi (2.4 km) east of the Las Vegas Strip. Groundbreaking on the original 60 acres (24 ha) site was in April 1956, and the university purchased a 640 acres (260 ha) site in North Las Vegas for future expansion. The institution includes a Shadow Lane Campus, located just east of the University Medical Center of Southern Nevada. The university has been deemed a "research-intensive university" by The Carnegie Foundation for the Advancement of Teaching. The first college classes which would eventually become the classes of UNLV were offered as the southern regional extension division of the University of Nevada in 1951 in a classroom at Las Vegas High School. UNLV was officially founded by the Nevada Board of Regents as the Southern Division of the University of Nevada in 1957. The first classes were held on the current campus on the now historic post and beam Mid Century Modern Maude Frazier Hall designed by the award winning local architectural firm, Zick and Sharp.
