Guia Fortress sits on the highest hill on the Macau Peninsula, providing a commanding view over the entire city and both bridges to Taipa. The 17th-century fort was built by the Portuguese to defend against Dutch and Chinese attack, and within its grounds stand the Guia Chapel — one of the few surviving examples of early colonial religious architecture in Macau, with unusual murals mixing Christian and Chinese iconography — and the Guia Lighthouse, the oldest Western-built lighthouse on the Chinese coast, still operational since 1865.
The fortress is part of the UNESCO-listed historic centre. The easiest way up is by cable car from the Flora Garden at the base; you can also walk up through the wooded hill paths. The views from the ramparts over the city, the Pearl River Delta, and on clear days into Guangdong province are the best in Macau.
