Lindenwold Castle

In 1912, it sustained a partial remodel to resemble Windsor Castle,[3] with Mattison commissioning Italian stonemasons and German craftsmen to create its regal iron gates.

As of 2012, the castle retained original elements such as a stairwell bordered by stained glass, gilded wallpapered ceilings, and carved marble fireplaces.

[1] On November 7, 2014, the United States Department of Interior issued a letter which determined the property eligible for listing on the National Register of Historic Places.

The complex was proposed to include "independent living, assisted living, and a memory unit" with "an indoor pool, fitness center, yoga studio, two movie theaters, a dog wash and dog run, art studio, multiple indoor and outdoor dining venues, bars and lounges, barbecue grills, fire pits, and a putting green.

"[1] On January 16, 2019, and made effective January 25, 2019, the Lindenwold Residential Associates LLC, a limited-liability company, became legally bound to uphold the terms of a deed of preservation easement granted to the Preservation Alliance for Greater Philadelphia, a not-for-profit "qualified conservation organization," which would be, in effect, the body charged with stewardship over the historic property.
