This stadium which, having 113.60 m diameter in the base is one of the biggest circular pavillions in the world comprises a 60 X 30 m sports field, four racing tracks and a veloromo. It also has two grandstands, with capacity for 6,300 seats, and all the necessary installations for holding any type of sporting or social event. For its construction, a system of prefabricated parts was chosen which, in essence, comprises the following: a series of reinforced concrete supports, placed in the periphery on individual foundations; and a metal sheet monolythic roof, in the shape of an inverted cone, with an 112 m free span without supports, hung from the supports and tensioned by a central reinforced concrete slab, on which the heating and ventilation installations have been placed. This roof, placed at a height of 22 m, weighs 445 tons. The construction is completed with the grandstand seats, statically separate from the rest of the structure, and made up of prefabricated angular components, resting on concrete frames made on site.
