What's the name of a big archway in Macau?

The ruins of Sao Paulo's Grand Pailou are the most representative places of interest in Macao. This is the front wall of St. Paul's Cathedral, completed on 1580. This cathedral is a fusion of European Renaissance and oriental architecture, which embodies the blending of eastern and western arts. Exquisitely carved, magnificent. More than 400 years ago, after the Portuguese invaded Macao, they also brought Catholicism to Macao. 1562, the Portuguese built this gothic church in Macao after several years and named it "St. Paul's Church". The pronunciation of Portuguese "Sao Paulo" is close to the pronunciation of "March 8" in the local dialect, so it is also called "March 8 Church". Later, the church was destroyed by fire twice. 1602, St. Paul's church was rebuilt again, and it was completed in 1637 35 years later. /kloc-a fire in 0/835 destroyed the church again, leaving only the front wall costing 32,000 silver, which became today's St. Paul's archway. At present, Sao Paulo archway is one of the main tourist attractions in Macao.
