The Torino Esposizioni, the hystorical building designed by Luigi Nervi in 1949, was converted into a temporary ice rink to host a number of ice hockey events at the 2006 Winter Olympics along with the Torino Olympic Palasport Stadio Comunale Area. The boards in the hockey rink are stiffer than in a permanent facility, while the glass has more give. The facility was converted into an ice rink by laying a sand base and refrigeration pipes into the base, and then freezing water ice atop the substrate. This is similar to the temporary outdoor rink the NHL used for its Heritage Classic game in Edmonton.
After the Olympics were complete, the arena returned to hosting fairs and exhibitions.

Parco del Valentino

This celebrated park extends along the left bank of the river Po at the foot of the hills, between the King Umberto I and Princess Isabella bridges. It is very close to the centre of town, and about one kilometre from the Porta Nuova main railway station.
It no longer is Turin vastest park, as its some 500,000 square metre area now ranks second after the 840,000 square metre Pellerina Park, Italy's most extended urban green area.
The park was opened in 1630 on a project by Carlo Cognengo di Castellamonte and later completed by the designer's son Amedeo in 1660. In 1864 it was partially redesigned by French designer Barillet with a better layout of avenues and lanes, little woods, artificial dales, a small riding-track and a mini-lake, later dried out and used as skating rink during the Winter season.
The great International Exhibitions of 1884, 1898, 19021, 1922, and 1928 were held in the park grounds. A pleasantly flowered dale crossed by streams and full of flowers beds, with a nearby rock garden was created for the 1961 Exhibition. The rose garden was created in 1965 and was later enlarged for the Flor 62 Flower Show.
