Dongwangyang Mountain (Colina da Guia), commonly known as Songshan, is the highest mountain on the Macau Peninsula, with a high altitude of 93 meters. The ancient name Qinshan (because it is shaped like a lullaby), originally a barren mountain, facing the sea in the east. The fort was built in 1622 (with a church and the oldest lighthouse in the Far East, and the coordinates of the longitude and latitude of Macau are based on the coordinates of the lighthouse), which is part of the historical city of Macau. In the 19th century, the Portuguese government planted pine trees, so it was called Songshan. Later, the park was opened up and became an important city lung in Macau. It is the best place for Macau's birds and flowers to stay away from the dust collector. It is the highest point of Macau's terrain. It is on the top of the mountain and overlooks the faces of Macau's various districts. The hilltop, which houses the ancient fort of the fort and the oldest lighthouse in the Far East's history, was built in 1865 and still shines all night around Macau, leading ships to sail.
