The splendid property known as Big Spring Farm, situated in Western Berks County, boasts an intriguing history that dates back to 1730, when William Allen, a wealthy merchant from Philadelphia, first conveyed the land. It is thought that the Allen family erected the two stone residences overlooking the picturesque 1-acre pond for their summer getaways. The political upheaval that followed the signing of the Declaration of Independence in 1776 eventually led to the Allens losing ownership of the estate due to the Divesting Act. Over time, various owners cultivated the land, but in the 1960s, Dr. Frederic B. Thomson, a local veterinarian, established an equine hospital on the property, focusing on thoroughbred care. The estate, named Big Spring Farm, is renowned for its spring-fed pond, which is considered to be the largest spring water aquifer of its kind east of the Mississippi. It is one of Berks County's most exquisite estates. The entrance to the farm is marked by a 1-bay garage size gatehouse. Stately century-old maples line the driveway, which leads to the primary entrance, service entrance, and a 3-bay carriage house featuring an apartment. The property spans 23.6 acres, with a considerable portion being fenced pastureland. Gentle slopes surround the 1-acre pond, and flagstone pathways lead to various outdoor features, such as Al Fresco terraces, an enchanting octagonal gazebo, a root cellar, and a stone spring house. The dock gazebo by the pond provides a romantic setting for evening gatherings. The main residence, a stunning over 6,300 square-foot structure, combines colonial elements from 1735 and 1740 with a beautiful 20th-century addition. The home's rich history is evident in its architectural details and original finish materials. Noteworthy features include the family room's fireplace, believed to have been salvaged from the original fire-damaged White House in Philadelphia, as well as striking fireplaces in the living room and formal dining room. The thick stone exterior walls of the home create substantial 24' interior window sills, perfect for displaying indoor plants or collectibles. The home's unique layout offers numerous possibilities for room utilization, making it ideal for hosting holiday gatherings, accommodating seasonal guests, and conducting grand formal events with its 18 rooms and 6 1/2 baths.
