We stopped for a day and 2 nights on our way between the Pantanal and Brasilia. It is a pretty and well preserved former state capital on a very modest scale but on the day we visited the town felt deserted. We couldn't enter the churches or museums and had to content ourselves with a quick wander up and down the historic core (~1-2 hrs max) before settling down in the little plaza to eat ice cream and watch a few families play. An enjoyable enough day but a site only recommended for those with a lot of time to use going out of their way to get there or for the very serious WHS enthusiast.
