Fiesta de la Integracion de Chuy in Chuy
Listed as an integration festival in the border town of Chuy, Uruguay's twin city with Chui, Brazil. Research found this concept is realized through two specific, well-documented events, the Festival Binacional del Bauru and the Carnaval Binacional Chui-Chuy, rather than a separately confirmed festival under the exact searched name.
Chuy sits at Uruguay's northeastern tip, its main street forming the literal border with the Brazilian town of Chui, and the two communities function in many respects as one urban area split by a line on a map.
