Dagsboro, incorporated in the early 1900s, is a town that is energized in summer by Delaware Route 26 beach traffic.

[4] It was named for John Dagworthy (1721–1784), a brigadier general of the Sussex County Militia during the American Revolutionary War.

[7] According to the United States Census Bureau, the town has a total area of 2.3 square miles (6.0 km2), all land.

Roads are the main method of travel to and from Dagsboro, and three state highways serve the town.

U.S. Route 113 is the most significant of these, passing along the west edge of town on a north-south alignment.

[12] Clayton Theatre opened in Dagsboro on February 2, 1949, with One Touch of Venus, a film featuring Ava Gardner, on its single screen.

In the 1950s, a soda fountain operated as Clayton Cut Rate Luncheonette in a storefront adjoining the theater.

Although the Clayton now uses digital projection equipment, it continues doing business as Delaware's last single-screen theater.
