Signal Hill – originally named "Big Stone Hill" due to the numerous granite boulders scattered across the mountain. In 1897, after Germany occupied Qingdao, a signal station and a radio station were built on the summit to direct ships entering and leaving Jiaozhou Bay, hence the name "Signal Hill." Today, Qingdao Signal Hill Park is located in the heart of the old town of Shinan District, Qingdao (at the intersection of Longshan Road and Qidong Road). Rising 98 meters above sea level, it serves as a central landmark of Qingdao's historic district and offers a spectacular vantage point for viewing the city's iconic scenery of "red roofs, green trees, blue sea, and clear skies."
