Exploring Worlds Largest Abandoned Mansion - Estimated At 256 Million

Lynnewood Hall is a 110-room Neoclassical Revival mansion in Elkins Park, Montgomery County, Pennsylvania. Currently undergoing renovations after sitting nearly vacant for years, it was designed by architect Horace Trumbauer for industrialist Peter A. B. Widener and built between 1897 and 1900. Considered the largest surviving Gilded Age mansion in the Philadelphia area, it housed one of the most important Gilded Age private art collections of European masterpieces and decorative arts, which had been assembled by Widener and his younger son, Joseph E. Widener.
