I am kind of attracted by this one particular ruins. The amount of people that visited the place everyday, the known local delicacies that you can sample for free on almost in front of all the shops on the way to the ruins, the somewhat wide and narrow streets full of people from anywhere in the world, it is just "magical".

Quoted from Wikipedia:

The Ruins of St. Paul's are the ruins of a 17th-century complex in Santo António, Macau, China. It includes what was originally St. Paul's College and the Church of St. Paul also known as "Mater Dei", a 17th-century Portuguese church dedicated to Saint Paul the Apostle.
