About the location (from Wiki):
The Ruins of St. Paul’s refers to the ruins of a 16th century complex in Macau including of what was originally St. Paul’s College and the Cathedral of St. Paul also known as “Mater Dei”, a 17th century Portuguese cathedral dedicated to Saint Paul the Apostle. Today, the ruins are one of Macau’s most famous landmarks. In 2005, they were officially enlisted as part of the UNESCO World Heritage Site Historic Centre of Macau.

Built from 1582 to 1602 by the Jesuits, the cathedral was the largest Catholic church in Asia at the time, and the royalty of Europe vied with each other to bestow upon the cathedral the best gifts. With the decline in importance of Macau, which was overtaken as the main port for the Pearl River Delta by Hong Kong, the cathedral’s fortunes similarly ebbed, and it was destroyed by a fire during a typhoon in 1835. The Fortaleza do Monte overlooks the ruin.

The ruins now consist of the southern stone façade—intricately carved between 1620 and 1627 by Japanese Christians in exile from their homeland and local craftsmen under the direction of Italian Jesuit Carlo Spinola—and the crypts of the Jesuits who established and maintained the Cathedral. The façade sits on a small hill, with 66 stone steps leading up to it. The carvings include Jesuit images with Oriental themes, such as a woman stepping on a seven-headed hydra, described by Chinese characters as ‘ Holy Mother tramples the heads of the dragon’. A few of the other carvings are the founders of the Jesuit Order, the conquest of Death by Jesus, and at the very top, a dove with wings outstretched.
