Most of the sights of interest are in Praça Girossóis, purportedly the second-largest municipal square in the world after the Red Square in Moscow.
Palmas’ layout is highly logical, but still confuses most first-time visitors. All quadras (blocks) are numbered, and the main avenues are named for their direction: ‘NS’ for norte–sul (north–south) and ‘LO’ for leste–oeste (east–west). Smaller ruas (roads), are named according to their quadrant – like ‘NO’ for the northwest or ‘SE’ for southeast – in relation to Praça Girossóis, the center of the city. Only Palmas' two main thoroughfares have regular names: Av Juscelino Kubitschek (known as Av JK) and Av Teotônio Segurado.
