The Danish West India and Guinea Company Warehouse is one of the oldest buildings in Christiansted's historic district, built in the 1740s as the primary storage and trading facility for the Danish colonial monopoly company. The long, two-story structure runs along the waterfront, its thick masonry walls and arched ground-floor arcade typical of the Danish Caribbean mercantile style. It served successive functions — warehouse, government offices, post office — across three centuries of changing ownership and political control.
The building now falls within the Christiansted National Historic Site and has been partially restored to show its original character. The arcade level with its open arches is particularly well-preserved. Together with the fort and the Scale House next door, it anchors the most visually coherent section of the harbor front, a stretch of architecture that looks much as it did when sugar and slaves were the economy of the island.
