In ZOO With Predators, Argentina

Henry I of England kept a collection of animals at his palace in Woodstock, which reportedly included lions, leopards, and camels. The most prominent collection in medieval England was in the Tower of London, created as early as 1204 by King John I. Henry III received a wedding gift in 1235 of three leopards from Frederick II, Holy Roman Emperor, and in 1264, the animals were moved to the Bulwark, renamed the Lion Tower, near the main western entrance of the Tower. It was opened to the public during the reign of Elizabeth I in the 16th century. During the 18th century, the price of admission was three half-pence, or the supply of a cat or dog for feeding to the lions. The animals were moved to the London Zoo when it opened.
• Modern era
The oldest existing zoo, the Vienna Zoo in Austria, evolved from the Imperial Menagerie at the Schönbrunn Palace in Vienna, an aristocratic menagerie founded in 1752 by the Habsburg monarchy, which was opened to the public in 1765. In 1775, a zoo was founded in Madrid, and in 1795, the zoo inside the Jardin des Plantes in Paris was founded by Jacques-Henri Bernardin, with animals from the royal menagerie at Versailles, primarily for scientific research and education. The Kazan Zoo, the first zoo in Russia was founded in 1806 by the Professor of Kazan State University Karl Fuchs. The Zoological Society of London, founded in 1826 by Stamford Raffles, adopted the idea of the Paris zoo when they established the London Zoo in Regent's Park in 1828, which opened to paying visitors in 1847.Dublin Zoo was opened in 1831 by members of the medical profession interested in studying animals while they were alive and more particularly getting hold of them when they were dead. The first zoological garden in Australia was Melbourne Zoo in 1860. In the same year, Central Park Zoo, the first public zoo in the United States, opened in New York, although in 1859, the Philadelphia Zoological Society had made an effort to establish a zoo, but delayed opening it until 1874 because of the American Civil War.
The zoo in Thiruvananthapuram, Kerala, India is one of the oldest in the country, and was established as an adjunct to the Museum in 1857 by the erstwhile Maharaja of Travancore in order to attract more visitors.
