Fort San Domingo, located on the hilltop overlooking the estuary of Danshui River, was established by Spanish in 1628.  In 1642, the Dutch moved up from southern Taiwan, drove away the Spanish, and built “Fort Antonio” near the ruin of Fort San Domingo.  Since the local inhabitants in Danshui at that time referred the Dutch as red hairs, the fort was nicknamed as the “Hong Mao Chen”, meaning the fortress of red-haired people.  As a record of the Spanish occupation, we now inherit the name to represent the historical site.The main structure of Fort Antonio is a two story square building. The sturdy and deep foundation, and thick walls with the mix of stones and bricks provide the fort strong and effective fortification.  Following the opium war, Danshui harbor was open for commercial use.  The British government leased the fort from the Qing government as their consulate.  Some modifications were made accordingly for the consul business.

　　To accommodate the need of consul and consul’s family, the consul’s residence was added later on the east side of the fort.  The Victoria period style building stands with its red bricks, verandas, and 4-sided steep roof, providing a warm and delicate atmosphere, which softens the mean military purpose of the fort.  The blending of the two different ambiences painted the green hill with unique and balanced beauty.
