Finados in Brazil is celebrated on November second. It is similar to Memorial Day in the states where people put flowers on the graves of their loved ones. It is a Catholic holiday. But it is different in that they also light candles on the graves to illuminate their way to heaven and pray for their departed ones.
In respecto the people I did not go to the cemetery to take pictures, but did today and some of the candles can still be seen.
The cemetery in Campo Verde is different than the one I have seen in Cuiabá. Notice the little "houses" built over the tombs with windows with curtains and of course, flowers. In the first picture you can see big "houses" in the background that are really graves.
