Estadio Municipal de Rio Maior
Rio Maior, Portugal
Rio Maior's municipal ground has spent most of its life as somebody else's home. Sporting CP's B side used it in 2012–13; União Desportiva Vilafranquense played there from 2019 through; União de Leiria, Marítimo and Estrela da Amadora have each borrowed it for the odd fixture. The club that once anchored the place, União Desportiva de Rio Maior, has suspended activity, and the local side on the pitch now is Rio Maior Sport Club, in the Santarém District Championships.
The tenancy that changed the ground was Casa Pia AC's. The club came up needing a top-flight venue, and its first Primeira Liga home match here, against Sporting CP on 18 August 2023, ended 2–1 to the visitors. Later that year the lighting, the sound system and the seating were reworked — Casa Pia paying part of the bill — to bring the stadium up to the Silver category Liga Portugal sets for the first division. That same 2023–24 season produced a crowd of 6,981.
It was never built as a football-only bowl. The pitch, 104 by 68 metres, sits inside a 400-metre athletics track, one piece of the Complexo Desportivo de Rio Maior, which the municipal company Desmor runs for the city council. In January 2026 the storm named Kristin went through the complex, bringing down trees and damaging roofing, with matches still put on while the clearing-up went ahead.
