National Historic Landmark-Borough House

Constructed in 1821, the Borough House Plantion complex contains the oldest and largest collection of high style pise de terre (rammed earth) buildings in the United States.

Six of the 27 dependencies and portions of the main house were constructed using this ancient technique, which was introduced to this country in 1806 through the book RURAL ECONOMY by S.W. Johnson.
