It also has an auxiliary training center with natural turf and open basketball and volleyball courts.

The stadium was built in 1932 by the Italian authorities with architect Armando Bernabiti, based on an ancient Hellenic U-shaped stadium, with stands on three sides, and was then called Arena Del Sole (Sun Arena), there are reports that in 1936 with the change of commander of the then Italian Dodecanese, from Mario Lago to Cesare Maria De Vecchi, the stadium was renamed "Stadio Mussolini", but there are no valid sources.

In the early 1980s, the outer wall of the stadium was about 250 cm., then doubled, and thus lost its original Italian form, but not in the auxiliary training center.

In 2020 the wall at gates 4-5 was repaired in its early Italian form and with the exact same alabaster stones used in its construction in 1932.

In 2021, a fund was approved for the renovation and maintenance of the stadium and the facilities, but they will not change its original appearance due to the fact that it is part of the Service of Modern Monuments.
