The Guia Fortress is a 17th-century colonial military fort, chapel, and lighthouse complex. It is in the St. Lazarus Parish, Concelho de Macau, Macau.
The complex is part of the UNESCO Historic Centre of Macau World Heritage Site.
The lighthouse was constructed between 1864 and 1865, the first western style lighthouse in east Asia or on the China coast. The lighthouse stands at Guia Hill, which stands at 91.4 metres (300 ft) tall, and has a light visible for some 20 miles in clear weather conditions. The complex was built upon the highest point on Macau, Guia Hill, and named after the same location. Today, the site is a tourist destination.
