The five smallest stadiums in the 2025/26 Champions Cup

These compact stadiums punch above their weight, hosting elite clubs despite limited capacity, challenging locations or temporary facilities.

Here, we look at the five smallest venues in this year’s competition and explore what makes each one unique.

In a town of just over 40,000 people, the home of Castres Olympique stands out as a symbol of small-town sporting achievement. Stade Pierre-Fabre holds 12,300 spectators—more than a quarter of the local population—making it one of the smallest grounds in the Top 14.

Named after Pierre Fabre, the influential pharmaceutical magnate who owned the club from 1988 until 2013, the stadium reflects his lasting legacy. Despite its modest scale, Castres have consistently defied expectations, most memorably when they captured the Top 14 title in 2018.

The ground’s intimate setting and tightly packed crowds help fuel a unique atmosphere, reinforcing Castres’ reputation as one of French rugby’s great overachievers.

Located in Barton-upon-Irwell, the CorpAcq Stadium has served as Sale Sharks’ home since the 2012–13 season. Originally built to replace Salford RLFC’s old Willows ground, it accommodates 11,404 spectators, placing it among the smallest venues in the Champions Cup.

Matchdays often draw criticism for reasons beyond the rugby, with fans highlighting poor transport links, limited amenities and the generally isolated setting.

Attendance numbers have fluctuated as a result, fuelling talk of a potential relocation. Altrincham is frequently mentioned, especially now that Sale likely shoulder more of the operating costs following Salford Red Devils’ financial issues.

While functional, the stadium’s long-term future remains uncertain as the club considers a move better aligned with supporter access.

As the smallest ground in the Premiership, Saracens’ home in Hendon offers a compact but adaptable 10,500-seat setting. Known as StoneX Stadium since 2021, it has long served multiple sports, hosting not only rugby union but also the London Broncos and American football events such as BritBowl.

An artificial surface and strong training facilities add to its versatility, while temporary expansions can push capacity to around 15,000 for major European fixtures. Previously branded Allianz Park, it remains a practical base for one of England’s most decorated clubs, even if generating a consistently intense atmosphere can be a challenge.

Its flexibility continues to make it a suitable venue for high-level domestic and international competitions.

Set in Glasgow’s West End, Scotstoun Stadium functions as both an athletics venue and the home of the Glasgow Warriors. The team began training there in 2009 and moved competitive fixtures to the site in 2012–13, playing on a World Rugby-approved artificial surface.

The stated rugby capacity of 9,708 relies heavily on temporary stands, and the permanent seating is significantly lower, making it one of the smallest venues in elite European rugby. The stadium has hosted major events, including the Scotland Sevens from 2012 to 2015, and is scheduled to stage athletics at the 2026 Commonwealth Games.

Despite its size, Scotstoun has been central to Glasgow’s rise, including their impressive push toward the 2024 URC title.

Next to the enormous Murrayfield complex sits The Hive Stadium, Edinburgh Rugby’s purpose-built home completed in February 2021. With a 7,800-seat capacity, it finally provided the club with a ground appropriately sized after years of playing in the cavernous national stadium, where atmosphere often suffered.

Built on former training pitches beside the Water of Leith and the Saughtonhall neighbourhood, it offers an intimate, close-to-the-action environment. Its opening coincided with the COVID-19 period, delaying public attendance until September 2021, when Edinburgh hosted Newcastle Falcons in a pre-season match.

The Hive has since become central to the club’s identity, delivering a modern and vibrant matchday experience in stark contrast to its much larger neighbour.
