I did a reverse image search. That is the Benjamin Tallmadge House, located on North Street in Litchfield, Connecticut. It is a notable example of High Georgian architecture. Originally built around 1775 for Thomas Sheldon, it was purchased in 1782 by Benjamin Tallmadge, a former officer in the Continental Army and chief intelligence officer for George Washington during the Revolutionary War. Tallmadge also founded a notable spy ring in New York. He married Mary Floyd, daughter of William Floyd, a signer of the Declaration of Independence. In Litchfield, he became a merchant (in partnership with Oliver Wolcott, Jr. and Julius Deming) and was president of Phoenix Bank (later the First National Bank of Litchfield).
Tallmadge expanded the house by adding two-story Tuscan-columned porticos on the north and south sides, enhancing its grandeur. Over the years, the house underwent various modifications and ownership changes. It was owned in the 19th century by William Curtis Noyes and later by his daughter, Emily Noyes Vanderpoel, who used it as a summer residence. In the early 21st century, efforts were made to restore the house to its former elegance, including removing later additions and modernizing essential systems while preserving its historical character. Today, the Benjamin Tallmadge House stands as a testament to its rich historical legacy and architectural significance in Litchfield.
