Green Mansion House

Main St., Kenton, DE
The Green Mansion House was built as a town dwelling during the initial development of the town of Kenton. Philip Lewis, in arranging for its construction, had the building erected in a manner very similar to many of the brick farmhouses standing in Kenton Hundred. The original brick block is a one room plan dwelling and now functions as a kitchen wing. The frame block contains the public living space and is arranged in the formal vocabulary of a 3-bay, centerhall-plan dwelling. The combination of the two diverse floor plans has created a unique dwelling in that the nineteenth century use of a one room plan in brick is linked to a more modern and major frame addition. The usual practice in Kenton Hundred is to have the brick section retain its use as the major block and the frame additions serve as a minor wing. This house is therefore eligible under Criterion C as an example of a reversal of the usual building practice and tradition of Kenton Hundred. The house is also eligible under Criterion A for its association with Philip Lewis, the initial developer of Kenton, but more importantly for its association with and used by John Green as his principal residence while he participated in encouraging the growth of the town.

Kent County, located in the state of Delaware, has a rich and diverse history that dates back to the colonial era. The area was originally inhabited by the Lenape people before European settlers arrived in the early 17th century. The first permanent European settlement in the county was established by the Dutch in 1631, but they were soon displaced by the English who took control of the region.

During the 18th century, Kent County played a significant role in American history, particularly during the American Revolution. The county's proximity to important waterways, such as the Delaware River, made it a strategic location for trade and transportation. Dover, the county seat, became the state capital in 1777 and hosted the state's constitutional convention. It was also the site of the historic Golden Fleece Tavern, where the Constitution of Delaware was ratified.

In the 19th century, Kent County experienced economic growth and development, largely centered around agriculture and industry. The county became known for its large agricultural estates, such as Dover's Green Thatch Plantation, which contributed to the region's prosperity. With the advent of railroads, transportation became more efficient, allowing for easier movement of goods and people.

In the 20th century, Kent County saw further growth and diversification. The establishment of Dover Air Force Base during World War II brought economic opportunities and employment to the area. Additionally, the county's location between two major cities, Philadelphia and Baltimore, contributed to its role as a transportation hub and a growing business center. Today, Kent County continues to thrive as a blend of agricultural, industrial, and residential communities, while also preserving its historical heritage through numerous museums, historic sites, and landmarks.
