There were originally reef rocks in the waterway, which made it very difficult for large ships to pass. As a result, the Port of Kaohsiung was not chosen to be a main trade port when the Dutchmen evaluated the ports along the coast. When the Harbor Construction Project began in 1908, the reef rocks were removed, water depth of the port was increased, and many facilities were also established on the reclaimed land. Therefore, the Port finally began to develop and reached its prosperity, and became the largest international trade harbor in Taiwan. It also used to be the world’s third largest container port.
