Casa Pia AC is a historic Portuguese football club based in Lisbon, currently competing in the Primeira Liga, the top flight of Portuguese football. The club plays its home matches at the Estádio Pina Manique. Founded in 1920, the club is traditionally associated with the iconic green and white stripes. Casa Pia has a unique identity as a club originally connected to a charitable educational institution (the Casa Pia). Their early history saw them as a respected amateur side. After decades in the lower leagues, the club's modern era has been defined by a remarkable resurgence, achieving promotion to the Primeira Liga in 2022 after an absence of over 80 years. This achievement, built on a solid defensive structure and shrewd recruitment, marks the club's key era in the contemporary period. Currently, Casa Pia establishes itself as a tough, organized top-flight side capable of upsetting traditional giants. The club's fan base, though smaller than Lisbon's "Big Three," is incredibly passionate and proud of their team's unique story and against-the-odds success. Casa Pia AC is one of Portuguese football's most inspiring comeback stories.
