Ruins Of St. Paul’s, Macau, PRC

When completed in 1640, St. Paul's Church was one of the largest Catholic churches in Asia. School of St. Paul's College, a Jesuit training center, was the first Western university in the area. The complex was a project of the Portuguese, who colonized Macau in the mid-16th century and remained there until 1999. After serving as a house of worship for almost 200 years, the church was destroyed by a fire in 1835.

All that remains of St. Paul is a single facade. The looming silhouette retains its original stonework and sculptural elements. Interestingly, it was Christian exiles in Japan who were responsible for the carvings that blend Jesuit and Oriental imagery. Visitors can also visit the church's crypt, which houses a small collection of religious relics and artwork.

Today, the Ruins of Saint Paul don't really attract pious people — but fervent Instagrammers, who jostle for photos on the vast stone steps.
