Watch the world go by at Praça da Graça. If its well-trodden pathways could talk, this historic town square would have some amazing tales to tell.
When you've finished exploring this public square in Parnaíba, why not make your way to Parque Nacional Sete Cidades, Parnaiba Shopping, and Lagoa do Bebedouro? They're not very far from Praça da Graçan and also popular with travelers.
