Penguinarium
A penguinarium is a vivarium for penguins intended to simulate aspects of their natural environment.
Penguinariums date back at least to 1968, when the Detroit Zoo opened the first in North America and possibly the world. The Detroit penguinarium expanded in 2015 with a US$21 million overhaul funded in part by a US$10 million donation - the largest in the zoo's history - from a single donor. When completed, the penguinarium is expected to be 24,000-sq-ft.
As of 2005, the world's largest penguinarium was located on the Spanish island of Tenerife, where twelve tons of artificial snow were generated daily for the penguins at Loro Parque aquarium.
