A rare and largely unaltered survivor of “Millionaire’s Row”—Madison Avenue in Morris Township, where large and elegant estate homes were once owned by Gilded Age millionaires—will be open to the public when Alnwick Hall, known in recent years as “The Abbey,” opens for the designer showhouse “Mansion in May” this spring. Funds raised from the showhouse, which will be held every day in May, will help establish the new Center for Nursing Innovation and Research at the Morristown Medical Center. With more than 20,000 square feet, the brick mansion has attracted the attention of leading designers from New Jersey, New York and Pennsylvania who will transform 42 interior spaces for public and private tours and events. The stately home, designed by architect Percy Griffin, was built between 1903 and 1904 for Edward Peter Meany and his wife Rosalie. It was modeled after various 15th- and 16thcentury English estates, including Alnwick Castle in Northumberland, England. Meany was legal counsel for the American Telephone and Telegraph Company for many years and was later appointed to the post of Judge Advocate of the New Jersey National Guard.
