A penguinarium is a vivarium for penguins intended to simulate aspects of their natural environment.
[1] Penguinariums date back at least to 1968, when the Detroit Zoo opened the first in North America and possibly the world.
[2][3] The Detroit penguinarium was 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.
[3] In April 2016, the Polk Penguin Conservation Center opened at the Detroit Zoo becoming the world's largest penguinarium.
[5] As of 2005, the world's second 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.
