[6] According to the United States Census Bureau, the town has a total area of 0.8 square miles (2.0 km2), all of it land.

The present town of Eastville is situated near the sites of the first European settlements established on the Eastern Shore of Virginia.

[8] By the last quarter of the 17th century, Henry Matthews had settled on the tract of land covering the present town.

[9] The first courthouse was completed in 1690 and a small community developed to serve the needs of the court called “The Horns,” named for the several peninsulas of land which extended west into the Chesapeake Bay from the area.

[11] The last decade of the 18th century and the first quarter of the 19th century saw significant growth and development, including the construction of a third courthouse in 1795, the building of a tavern adjacent to the court green, and several large homes which remain a core part of the town's historic landscape today, including Cessford, Park Hall, and Ingleside, all examples of Georgian and Federal architecture.

[12] The town was known as Northampton Court House and Peachburg until the name Eastville was officially given to the community around 1800.
