Estádio Joaquim Américo Guimarães

Estádio Mario Celso Petraglia (Formerly named Estádio Joaquim Américo Guimarães) locally known as Arena da Baixada, is a stadium located in Curitiba, the state capital of Paraná, Brazil. It is the home stadium of Club Athletico Paranaense, and has a capacity of 42,372 people. The stadium was the first in Brazil to sell its naming rights; it was known as Kyocera Arena between 2005 and 1 April 2008 and Ligga Arena between June 2023 and August 2025. It was the first retractable roof stadium built in South America. With Curitiba selected as one of the host cities of the 2014 FIFA World Cup, the stadium was rebuilt from 2012 to 2014. Its capacity was expanded to 42,372 seats. Located in the Água Verde borough near the center of Curitiba, the history of the stadium began in the early twentieth century, when in 1914, Joaquim Américo Guimarães (1879–1917), then president of the International (the forefathers of Club Athletico Paranaense), led the construction of the then Arena da Baixada stadium. Athletico came into existence ten years later, inheriting the assets, including the stadium.
