The Prudential Lions were installed in Branch Brook Park, Newark, NJ in 1959 as a present from the Prudential Insurance Company of America.  The Lions are carved limestone companion sculptures depicting seated male lions, each with a front paw resting on a sphere.  They are approximately seven feet tall and weigh 2,900 pounds each.  Sculptor Karl Bitter created them in 1901 to stand over the doorway of the Prudential Insurance Company in Newark.  They were moved when the building was demolished in 1956.  In 2011, the Branch Brook Park Alliance decided to restore the original statues, while at the same time creating precast concrete replicas for the Park, which can be see here.

In January 2011, Kreilick Conservation, LLC began work on the original Lions.  The Lions suffered from surface soiling and biological growth, paint coatings, gypsum crusts, graffiti, and a loss of detail.  Kreilick Conservation oversaw the de-installation, transportation, and re-installation of the Lions by George Young Company.  The conservation treatment included archival research, petrography, cleaning, paint removal, water-misting, graffiti removal, desalinization, consolidation, restoration, and reconstruction.  Highbridge Materials Consulting, Inc. conducted the petrographic analysis.  Graffiti removal involved an array of techniques, including chemicals, baking soda blasting, steam cleaning, laser cleaning, and mechanical removal.  Restoration with clay was used to mock-up areas that were reconstructed later with Jahn Restoration Mortar and stone Dutchman.  After treatment, the Lions were installed outside the Hall of Records in Newark, NJ.
