The Ruins of St. Paul's is the most visited historic site in Macau although what remains standing is the facade of what was originally the Church of Mater Dei which was built by the Jesuits in 1602 but was destroyed by fire in 1835. The ruins of St. Paul's College stand adjacent to the church.
In 2012, some 28 million tourists came to Macau, which had a population of just over 500,000. Many of these tourists came from Hong Kong and mainland China. Five million tourists arrived by planes, exceeding the total number of visitor arrivals in the Philippines, a country of over 100 million.
The average temperature in Macau (22.7 degrees Celsius) is about four degrees cooler than in the Philippines (26.6 degrees). Aside from St. Paul’s, a tour of Senado Square leads to a public venue paved with wave-patterned stone mosaic. It is also famous for its souvenir shops and stores.
