Langdell Hall is the largest building of Harvard Law School in Cambridge, Massachusetts.

The frieze is inscribed with the maxim, "Non Sub Homine Sed Sub Deo Et Lege" from Henry de Bracton, meaning "Not under Man, but under God and Law."

The front features Ionic columns and the interior woodwork throughout the building was dark oak.

The renovations expanded the library, which now takes up most of the building, with the exception of two classrooms—the Vorenberg and Kirkland & Ellis.
