University of Maryland Rehabilitation & Orthopaedic Institute is a rehabilitation hospital located along the border of the Forest Park neighborhood of northwest Baltimore City and Woodlawn in Maryland.

The James Lawrence Kernan Hospital was built between 1860 and 1867 as Radnor Park, a two-story, five-bay, Victorian mansion.

The additional surrounding 1920s-era hospital structures were built in a style that blends well with the old historic mansion and its grounds.

James Lawrence Kernan (1838–1912), was a theater manager and philanthropist of the late Victorian and early Edwardian eras in Baltimore.

The "rathskeller" in the basement of the hotel (later also known as the "marble bar") was the site of the first "jazz band" music in the town when it opened in 1903.
