Historic Aldie Mansion
Aldie’s story is rich with history, and its survival is the result of a cooperative effort at preservation.
Heritage Conservancy’s Headquarters
At 85 Old Dublin Pike in Doylestown, PA, Aldie Mansion is a fitting home base for Heritage Conservancy, a nonprofit membership organization whose mission is to preserve and protect our natural and historic heritage.
Aldie Mansion began its history as a beloved private residence built by William and Martha Mercer. Commissioned as an ode to the English Tudor manor, this stately 1927 mansion evokes a time in America when craftsmanship reached its peak as an art form. The Aldie grotesques, intricate brickwork, antique tiles, ornate chimneys, and charming garden ornaments have been faithfully preserved as part of Bucks County’s unique artistic and cultural heritage.
In fact, William Mercer himself sculpted many of the mansion’s architectural details. William Mercer was the younger brother of Henry Mercer, Bucks County’s renowned tile maker and concrete sculptor, and artistic talent ran in the family. William’s artistry can be seen throughout the mansion, in its decorative ceiling reliefs and ornate mosaic fireplaces.
William and Martha Mercer were renowned hosts during their years living at Aldie, and they regularly welcomed international luminaries into their home. As you stroll about, it is easy to recall the spirited evenings when Groucho Marx joked at the dinner table and the von Trapp family caroled in the Great Hall.
In the most recent chapter in its story, Aldie Mansion is a model for the adaptive reuse of a historic building, hosting professional offices and events. Aldie is a premium Bucks County event venue for weddings, parties, conferences, and more. And revenue from events helps fund the Conservancy’s community programs and preservation work around the region.
