Pamplona – Estadio El Sadar

In May 1965, the directors at CA Osasuna decided that the old Campo de San Juan had more potential as a piece of real estate than a redeveloped, modern stadium. So the site was sold for 40 million pesetas and a new plot of land was purchased for 10 million pesetas a couple of kilometres to the south of Pamplona. Tomás Arrarás was charged with designing the two-tiered fully enclosed stadium and worked commenced in October 1966 on the 51 million peseta project. The new stadium was named El Sadar after the Rio Sadar that runs to the west of the site. It had an initial capacity of 25,000 of which 7,000 was seated. The stadium opened on 2 September 1967, but unusually Osasuna did not take part in the first match. That honour fell to Real Zaragoza and Vitoria Setubal, who were invited to compete in a triangular tournament with the hosts.

El Sadar before the fences and the main stand went up

Whilst the move was considered necessary for the long term future of the club, the construction had left the club with little if anything to spend elsewhere and this was reflected in the team’s performance. At the end of the 1967-68 season, Osasuna finished a lowly fifteenth in La Segunda and dropped to the Tercera for the first time in twenty years. The following decade saw a continuous journey back and forth between the second and third divisions before finally, Osasuna left the Tercera behind in 1977. After two seasons of mid-table finishes, the club put together an impressive run of form that saw El Sadar become a fortress. Osasuna won 17 of their 19 matches at home and eventually secured third place and a return to La Primera. Incredibly, despite one of the smallest budgets in La Primera, Osasuna defied the odds throughout the 1980s and whilst there were a few close run-ins with relegation, more often than not, the club achieved a mid-table finish. This stability in the top division prompted the next phase of the stadium’s development.

The Nueva Tribuna takes shape over the existing stands

In 1989, a new Tribuna was added to the west side of the ground at a cost of 561 million pesetas. This was however privately funded and Osasuna having cleared their liabilities, remained debt-free. The new stand was an impressive addition, with a deep cantilevered roof that hovered over the lower tier and a sweep of red seats raked at an alarming angle. As a result, the capacity of the stadium increased to 30,000, with 12,000 seats. This time, Osasuna thrived on the improved surroundings and finished fourth in the league earning a place in the UEFA Cup. In the early 1990s, new legislation laid down by the Spanish Federation stipulated that all clubs in the top two divisions needed to become a public limited company, unless that is, they were fans co-operative. Real Madrid, Barcelona, Athletic Bilbao and Osasuna were and still are owned by their fans and therefore escaped the change. Whilst their status off the field remained unaltered, Osasuna saw the break up of their best ever team and dropped to La Segunda in 1994. The club did not challenge for the promotion spots as expected and very nearly dropped into Segunda B at the end of the 96-97 season. Two seasons of mediocrity followed before promotion back to the top tier was sealed with the runners-up berth in 1999-00.

Estadio Reyno de Navarra… or El Sadar to the locals

Osasuna remained in La Primera until 2014, mostly avoiding relegation by the skin of their teeth, but they also managed to emulate that great team of 90-91 with a fourth-place finish in 2005-06. A season earlier and Osasuna reached their first final of the Copa del Rey, where they lost 1-2 after extra time to Real Betis. El Sadar was converted to an all-seat arena in the late 1990s reducing the capacity to 20,000 and the pitch was lowered by two metres in 2003, allowing room for a few more seats, but also improving the site lines. In December 2005 the Navarrese parliament approved the payment of 4.2 million euros to the club which resulted in El Sadar becoming the Estadio Reyno de Navarra, or Kingdom of Navarra Stadium, to tie in with the Region’s tourism slogan.

Tall ‘n’ Handsome – The main Tribuna at El Sadar

Given the club’s top-flight standing and tidy stadium, it may surprise some that La Selección has never paid a visit. Well, it should be remembered that to many, Navarra is considered to be part of the wider Basque community and put simply, the Spanish National side would not be welcomed by some in these parts. The stadium has witnessed “International” football as the La Selección de Navarra played three matches here during the mid-2000s. Osasuna’s relegation from La Primera in 2014 and the club’s impending financial meltdown, led to the sale of the stadium to the regional government in November 2014. Security-related renovation work saw the capacity drop to 18,761 in the summer of 2015. Osasuna returned to La Primera in 2016, but dropped back again a year later, however promotion back to the top flight in 2019 saw renewed hope on and off the pitch.

El Sadar – No longer owned by Osasuna

As the stadium reached it’s 50th anniversary, the club looked to redevelop many of its ageing elements. With it being a fan-onwed club, the socios were engaged and presented with 5 designs that would bring El Sadar into the 21st Century. The winning design was called “Muro Rojo”, or Red Wall, and was the work of OFC Architects. The most significant development was the addition of a C-shaped upper tier to the three lowest sides of the stadium. This would bring the height of the new tier almost up to the level of the existing Tribuna, and allow for the addition of a single roof of uniform height. Rail-Seating for 1,300 was added for home supporters, an addition that will only crank up the volume at one of Spain’s most atmospheric stadia. New commercial outlets and offices were added at ground level, whilst an outer skin of perforated steel, as seen at El Malecón, completed this very impressive design. Work began on the €17.8m project in October 2019, and although slowed by the COVID-19 pandemic, was completed 17 months later, when Osasuna hosted Sevilla FC on 22 February 2021, albeit with no supporters present.


For much of Osasuna’s tenure in La Primera, El Sadar has been a fortress. On many occasions, it has proved to be the club’s most potent weapon and many top teams have found points hard to come by. The redevelopment of El Sadar seems to have met with universal praise, and I am sure many clubs will look at the cost of the project and its transformation and  rethink their own plans. However, it will only be when fans return to El Sadar, that you will see what an truly amazing feat Osasuna has achieved.
