In 1995, after repair and maintenance work the fronton was renamed after Mariano Juaristi Mendizábal who played with the pseudonym of "Atano III", often considered one of the best pelotaris of all time.

The main modalities played in the Atano III fronton are Hand-pelota and Paleta-rubber.

Atano III is one of the frontons which held one of the most important yearly competitions in the sport, the 1st Hand-Pelota Championship, with 40 finals played there until the current date.

[3] These are the most notable events held in the Atano III since the name change in 1995.

* In 1999, two separate finals were played, due to a disagreement between the two organising companies, Asegarce and Aspe: the Aspe final was played in the Atano III (as listed above), and the Asegarce one in the Astelena (won by Eugi over Elkoro, 22–11).
