Early history The original was donated to the city by noted pioneer and explorer
John Ball upon his death in 1884. Shortly after, another was added and this marked the beginning of additional amenities, including ponds, a
theater, a band shell,
playgrounds, ball fields,
trails, and the
zoo. City commission records provide the first mention of animals on the property in 1891, when there was a debate about whether city money should be used to purchase more animals to add to the existing wounded and orphaned animals. was started in 1949 with an opening date of June 1, 1950. During the 1950–1960s, John Ball Zoo was built in the hills of the property. In 2004, a ballot was put forward to voters in
Kent County to relocate the John Ball Zoological Gardens; the referendum was defeated, and the zoo will remain at its current location for the foreseeable future. rests in the shade in the African Veldt Exhibit In 2005, a new $75–100 million master plan for the zoo was made involving all of the zoo and property. Besides the existing
camels, African
veld,
chimps, petting zoo, and animal hospital exhibits, it reworks the whole zoo. The new plan for the zoo features a system of streams named "Grand Rivers of the World" that would connect the zoo to the property surrounding the zoo. On April 27, 2007, the zoo broke ground on the first phase of the new master plan, starting construction of a $4.1 million "BISSELL Lions of Lake Manyara" exhibit. The zoo has not had a lion since "Gilda", their last lion, died of old age in 2005. The exhibit was built for six lions, but only three were placed in the exhibit. On June 21, 2008, the new
green lion exhibit was open to the public. s in the Stingray Lagoon Kent County including in the 2008-2009 Capital Improvement Allocation half the cost of
renovation of the Monkey Island Exhibit. The other half of renovation is supposed to come from the zoo society. In 2014 the zoo formed a non profit to take ownership of the zoo independent of Kent county to help facilitate further growth for the institution. On July 8, 2016, the stingray lagoon exhibit was closed after all 18
cownose stingrays and three
spotted bamboo sharks died due to a mechanical malfunction. A heavy rainstorm, which shorted a pump circuit, was blamed for the deaths. The backup system intended to alert zoo officials of a pump failure also failed.
Inclined railway In August 2012, an inclined railway was opened at the zoo. A train of three cars linked together provides a four-minute ride to the upper areas of the park. The zoo calls it a funicular, but technically it is in the category of
inclined elevator since there are not two vehicles (or trains in this case) that counterbalance each other. In either case the configuration as a three-car train rather than one car makes it an unusual example. ==Animal collection==
