Mount Pleasant is one of the grandest homes ever built along the Schuylkill River, and was called "the most elegant seat in Pennsylvania" by John Adams. It is considered to be one of the greatest American houses of its type that is still standing on its original site. Mount Pleasant architect Thomas Nevell was an apprentice of Edmund Woolley, the builder of Independence Hall. The rooms feature craftsmanship from carver Martin Jugiez, one of Philadelphia's leading artisans.
