Stade Charles Mathon

Over the years and across the divisions, USO has adapted its stadium for professional rugby. Ten years ago, when the club moved up to the ProD2 division, it began the process of expanding the stadium, with the installation of lighting, the extension of the Ponceurs stand, the construction of an 800m² clubhouse and a building dedicated to the training centre.

The Charles-Mathon stadium entered a new dimension with its promotion to the Top 14. The stadium's capacity increased from 8,670 to 11,400, including 8,000 seats.

The Ponceurs stand was completely refurbished in 2011 to reach a capacity of 3,700 seats.

In 2013, the Mathon stand was refurbished, increasing its capacity from 640 to 1,720 seats, including a dressing room area with more than 300 seats, and a press area and Canal Plus TV control room on the top floor.

In 2014, a 500-seat extension, a 72-person box area and a panoramic lounge for up to 100 people were built on the Mathon South side.

The South End stand, built during the 2013/2014 off-season, is located behind the south posts and can accommodate 2,000 seated spectators.

The North End stand was built during the 2015/2016 off-season behind the north posts and can accommodate 1,000 seated spectators.

During the 2016/2017 off-season, the North Stand disappeared and the capacity of the South Stand was doubled to accommodate 4,000 spectators, bringing the total number of seats in the stadium to 10,000.
