Allen Fieldhouse is an indoor arena at the University of Kansas (KU) in Lawrence, Kansas. The arena, named in honor of Dr. Forrest C. "Phog" Allen, who coached the university's men's basketball team for 39 years, is one of college basketball's most historically significant and prestigious buildings. The actual playing surface is the James Naismith Court, honoring the inventor of basketball who established Kansas' basketball program and served as its first coach from 1898 to 1907.
