Lynnewood Hall

Lynnewood Hall is a 110-room Neoclassical Revival mansion in Elkins Park, Pennsylvania. It was designed by the architect Horace Trumbauer for the industrialist Peter A. B. Widener and built between 1897 and 1899. Lynnewood Hall is the second largest surviving Gilded Age mansion in the United States and once housed one of the most significant art collections in U.S. history, amassed by Peter and his son Joseph E. Widener and donated to the National Gallery of Art in 1942.

Peter Widener died at Lynnewood Hall at the age of 80 on November 6, 1915, after prolonged poor health. He was predeceased by his elder son George Dunton Widener and grandson Harry Elkins Widener, both of whom died when RMS Titanic sank in 1912. The building changed hands a few times over the subsequent decades, with large portions of the estate grounds sold off in the 1940s. It hosted a Bible Presbyterian Church seminary from 1952 until the late 1990s, when the property was abandoned.

In 2023, Lynnewood Hall was purchased by the Lynnewood Hall Preservation Foundation, which has announced plans to restore the house and grounds. The property was listed on the National Register of Historic Places in 2025.
