Lighthouses serve as important markers by which sailors steer their boats, and they make an important contribution to shipping safety. As a follow-up to “Lighthouses Postage Stamps (Issue of 2019),” Chunghwa Post has released a set of five stamps on the following lighthouses: the Chiutzu Shan Lighthouse, the Kuosheng Kan Lighthouse, the Peiting Tao Lighthouse, the Hualien Kan Lighthouse and the Taiping Island Lighthouse. Descriptions of their designs follow:1. Chiutzu Shan Lighthouse (NT$8): Located atop Chiutzu Shan Hill on the west side of Keelung Port, the lighthouse was built in 1956. The first lighthouse designed and constructed in Taiwan by ROC citizens, it features a white square tower made of reinforced concrete. It is not currently in use.2. Kuosheng Kan Lighthouse (NT$8): Located at Kuosheng Kan in the Cigu District of Tainan City, the lighthouse was first constructed in 1957. It acquired its current appearance when it was rebuilt in 1970. The square tapered steel tower, painted black and white in alternating sections, is the westernmost lighthouse on Taiwan proper.3. Peiting Tao Lighthouse (NT$8): Located atop a hill on Peiting (“north ting”) Tao in Kinmen County, the round white lighthouse was built in 1882 of brick. Together with the lighthouse on Tungting (“east ting”) Tao, it creates the appearance of a pair of horns.4.
