[citation needed] The main sports of the club are football, handball, basketball, futsal, athletics, and rugby union.

In his memory, Belenenses erected a mausoleum at the Restelo stadium, where Porto, whenever they play there, lay a wreath in honor of the player, in one of the oldest traditions in Portuguese football.

[5] The club were runners-up in the league in the 1954–55 season, level on 39 points with Benfica, losing the title just four minutes from the end with a draw against Sporting.

The following year, Belenenses moved to the Estadio do Restelo, which involved a large investment and the sale of the best players, resulting in quality diminishing.

In the first leg, they lost 2–0 in the Camp Nou, winning 1–0 at the Estádio do Restelo with Mapuata scoring, coached by Marinho Peres, a former Barcelona player.

[9] On 27 May 2007, coached by Jorge Jesus, Belenenses reached their first Taça de Portugal final since their 1989 triumph, but were defeated 1–0 by Sporting CP.

During the 2014–15 season, Belenenses finished the championship in sixth place, thereby returning to European competition, qualifying for the 2015–16 UEFA Europa League.

So from the 2018–19 season, Belenenses SAD (the professional team) play their Primeira Liga home games at Estádio Nacional, whereas CF Os Belenenses registered an amateur team in 1ª Divisão Distrital de Lisboa, the equivalent to the Sixth Division (lowest Portuguese division), with the support of the majority of fans and club members.

[13] Since then, Belenenses have climbed up the division five times in a row, until they reach professional competition again in 2023, equaling the world record.

Belenenses' first win in professional competition came at Tondela, in a game they won 1-0 and the scorer was André Serra, the only player in the squad to have made the whole journey with the club from the bottom of the Portuguese football.
