Heaton Hall had been owned by the Holland family since the Middle Ages. In 1772, Sir Thomas Egerton, 7th Baronet (later the 1st Earl of Wilton), commissioned the fashionable architect James Wyatt to design a new home for his young family. Wyatt's neo-classical masterpiece was built in phases and was mostly completed by 1789. The hall has been a Grade I Listed Building since 1952 and has been called "the finest house of its period in Lancashire". It is built of sandstone and stuccoed brick, in a traditional Palladian design with the entrance on the north side and the facade on the south.
