DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The circa 1857 Blackstone House is a one and one-half story structure with an L-shaped plan. Despite later modifications to the rear porch, the Georgian Revival style house has retained many of its original features and materials. For more than 150 years, the house and outbuildings have been part of the cultural landscape of the Seip Earthworks. The Blackstone property is historically significant as an intact example of mid-nineteenth century residential and agricultural architecture.

The Seip Earthworks were built at a monumental scale by an indigenous tradition, presently referred to as the Hopewell Culture. The complex includes a large circle, just over 1500 feet in diameter, which intersects a smaller circle, approximately 750 feet across, and a square which intersects a smaller circle, approximately 750 feet across, and a square which is approximately

1080 feet across. The house was built on part of the large circle of the prehistoric earthworks. It is on the north edge of the large circle. The portion of the large circle occupied by the house is believed to be one of the least-disturbed sections of the earthworks at the site; it was described as the only unrestored or unexcavated portions of the earthworks system.
