In our 3-hour walking tour, Sueli, an enthusiastic native of lovely Ouro Preto, did a wonderful job of providing context for what we were seeing. In a very interesting way, she explained the different architectural and artistic styles of the churches and other buildings we visited. And she explained the political, religious, and socioeconomic realities that shaped those styles at the time each was built. She also provided tips on where to eat and shop during the rest of my time here.
