In the Center of Oaxaca is Santo Domingo. I've seen some old churches in my day. When Conor and I went to France, we saw many, including Notre Dame. I've seen some in Ecuador, for example the Basilica in Quito (photos here and here, my children look so young!). However, I don't think I've seen a cathedral quite as splendid, adorned, and intricate as Santo Domingo. It took over 200 years to build it, and construction began in the 16th century. In the 90's it was restored. It's interior includes the use of more than 60,000 sheets of 23.5 karat gold leafing. It was mesmerizing. The ceilings and all the walls were so detailed and shiny! Even the smallest among us appreciated the magnitude of this cathedral.
