Guia Lighthouse, Maritime lighthouse at Guia Hill, Macau

Guia Lighthouse is a cylindrical white tower with yellow trim on Guia Hill in Macau. It has a domed red roof with a finial and weather vane, a glass lantern room ringed by a black metal railing, and two small rectangular windows with yellow surrounds. A smaller white building with yellow trim and a cross-topped pediment stands beside it.

The structure was built between 1864 and 1865 and was the first western-style lighthouse of its kind in the entire region. It marked a turning point in how European technology was introduced across Asia.

The lighthouse stands as part of a fortified complex that reflects Portuguese building traditions and shows how European seafarers shaped this region's maritime culture. Visitors can see the connection between the fortress and harbor that made this place central to trade in the area.

Access is gained by climbing the hill, with the path running through the fortified complex and varying in steepness along the way. It is advisable to wear comfortable shoes and allow time to explore the entire complex.

The lantern holds one of only two giant crystal projectors ever made, from a factory that has long ceased production; its beam reaches 16 nautical miles. Until 2023 the tower also displayed typhoon signals, a practice ended for staff safety when signal No. 9 or above was hoisted.
