Measuring about 3200 square meters, this ice rink was created in 2008 in the Zócalo plaza in Mexico City.
A claim for the new world's largest rink coming from Kazakhstan has a hitch. In preparation of the 2011 Asian Winter Games, a 10,500 square meter "rink" consisting of a 400m speed skating oval and two hockey rinks was built in 2010. Similar venues have existed (i.e. Pettit National Ice Center) without claiming to having the world's largest rink.
Other natural "rinks" often make the claim as the world's largest, such as the Rideau Canal in Ottawa, which is a popular skating venue while the water is frozen.
