Jaigarh Fort (Rajasthani/Hindi: जयगढ़ क़िला) is situated on the promontory called the Cheel ka Teela (Hill of Eagles) of the Aravalli range; it overlooks the Amber Fort and the Maota Lake, near Amber in Jaipur, Rajasthan, India. The fort was built by Jai Singh II in 1726 to protect the Amber Fort and its palace complex and was named after him.
The fort, rugged and similar in structural design to the Amber Fort, is also known as Victory Fort. It has a length of 3 kilometres (1.9 mi) along the north-south direction and a width of 1 kilometre (0.62 mi). The fort features a cannon named “Jaivana”, which was manufactured in the fort precincts and was then the world's largest cannon on wheels. The palace complex (Laxmi Vilas, Lalit Mandir, Vilas Mandir and Aram Mandir) located ), an armoury and a museum. Jaigarh Fort and Amber Fort are connected by subterranean passages and considered as one complex.
A monkey is any nonhuman primate, with the usual exception of the lemurs and tarsiers. Thus defined, there are three type of monkeys: (1)non-human hominoids (also known as apes), (2)old world monkeys, and (3)new world monkeys. However, only the latter two are currently considered "monkeys" by most biologists. There are about 280 known living species of monkey (260 if non-human hominoids are excluded). Many are arboreal, although there are species that live primarily on the ground, such as baboons. Monkeys are generally considered to be intelligent. Unlike apes, old and new world monkeys usually have tails. Tailless monkeys may be called "apes", incorrectly according to most modern biologists; thus the tailless Barbary macaque is called the "Barbary ape".
The New World monkeys (superfamily Ceboidea) are classified within the parvorder of Platyrrhini, whereas the Old World monkeys (superfamily Cercopithecoidea) form part of the parvorder Catarrhini, which also includes the hominoids (apes and humans). Thus, as Old World monkeys are more closely related to hominoids than they are to New World monkeys, the monkeys are not a unitary (monophyletic) group, and thus there is no scientific basis for biologists currently excluding non-human hominoids from the monkey category.
