Founded on the site of an earlier French settlement, Christiansted was laid out in a grid pattern with two market places. Market Square is located between Company and King Streets in the west end of town and Sunday Market is bounded by King's Cross and Queen's Cross Streets on the south side of Company Street. The Christiansted Historic District, which includes the Christiansted National Historic Site, illustrates a continuation of building activity since the Danish colonial era. Christiansted was laid out by Frederick Moth, later the first Danish governor of St. Croix. Moth planned streets, subdivided the town, built an eastern fort for protection, and established a series of building restrictions and codes. The Christiansted National Historic Site, administered by the National Park Service, includes buildings along the waterfront that illustrate the life of a colonial society based on a sugar-producing plantation economy. Notable buildings located within the Christiansted National Historic Site include Fort Christiansvaern and the Old Danish Customs House.

The headquarters of Christiansted National Historic Site, administered by the National Park Service, are located in Fort Christiansvaern in downtown Christiansted, St. Croix Island, U.S. Virgin Islands. It is open daily 8:00am to 4:45pm, Monday-Friday, and 9:00am to 4:45pm Saturday and Sunday. A self-guiding walking tour is available at the visitor center at the park headquarters. For further information call 340-773-1460 or visit the park's website. Fort Christiansvaern has also been documented by the Historic American Buildings Survey.
