This year, the Fonthill Castle in Doylestown is celebrating its 100th birthday.
Noted tile maker Henry Mercer built the 44-room castle out of reinforced concrete.
The interior walls, floors and ceilings are decorated with an incredible array of his handcrafted tiles.
Mercer’s uncle had lost a priceless collection of European armor in a fire – and Mercer was determined that his own showcase would never burn.
WHYY’s Emma Jacobs spoke with the Fonthill’s manager, Ed Rydell, who tells the story of the night Mercer performed a dramatic demonstration.
Fonthill has special tours about the building of the castle running through Labor Day.
