From the description:
Lindenwold Castle, an architectural treasure spanning nearly 24,500 square feet, was originally built in 1890. In 1912, the estate underwent a partial remodel commissioned by industrialist Richard Mattison, who employed Italian stonemasons and tradesmen to transform the residence into the Gilded Age castle that still stands today — inspired by the iconic Windsor Castle. The property gained cinematic fame as the backdrop for the 1966 film The Trouble With Angels, starring Rosalind Russell and Hayley Mills, and its 1968 sequel Where Angels Go, Trouble Follows. Today, Lindenwold Castle is surrounded by 104 upscale townhomes and single-family residences, along with a 250-unit luxury senior living complex — a vibrant and desirable setting in the heart of a thriving community. Ideally located with easy access to Route 309 and the Pennsylvania Turnpike. The building is currently approved for redevelopment into 11 luxury apartments or condominiums, along with premium office space. Fully approved plans are in place and ready for execution. Proposed plans have been approved by The Preservation Alliance for Greater Philadelphia. Inside, the castle retains its extraordinary original features, including elaborately hand-carved woodwork, massive marble fireplaces, hand-painted wallpaper applications, Gilded Age chandeliers, and stunning stained-glass windows — a rare preservation of craftsmanship from a bygone era. Lindenwold Castle represents a once-in-a-generation opportunity to revive and repurpose a true historic landmark and create the most architecturally significant and prestigious apartment or condo building in Montgomery County.
