Indonesian Jungle, Biotope pavilion in Troja, Prague, Czech Republic

The Indonesian Jungle is the largest biotope pavilion in a Czech zoo, built 2001–2004 at Prague Zoo on the site of the former monkey pavilion. It covers 2,900 m², of which 1,900 m² is the exhibition greenhouse, roofed by a self-supporting glass dome shaped as an irregular rotational ellipsoid with trapezoidal panes. A one-way visitor path passes two floors of exhibits, including a 16-metre, 2-tonne artificial tree in the centre.

Plans for the pavilion arose to replace the old monkey house, which had served the zoo for five decades. An architectural competition in 1999 was won by the studio AND (V. Danda, P. Ulman, J. Kosnar); construction ran from late February 2001 to October 2004, delayed by the 2002 flood. It opened on 29 November 2004 with President Václav Klaus present, at a cost of 185 million CZK.

The entrance atrium presents Indonesia as a region of thousands of islands, with a large map and educational panels. A cascading system of four tanks stands for an Indonesian river, holding fish and turtles such as the Amboina box turtle, and two wooden copies of local boats hang nearby.

The pavilion is entered through an atrium with a large map of Indonesia and four linked tanks representing an Indonesian river, then a one-way route climbs through two floors to an orangutan viewing point. The glass dome covers 1,900 m² of exhibition greenhouse; the outdoor orangutan enclosure added in 2005 measures 350 m².

In 2023 the pavilion saw the first short-tailed pangolin born in Europe, and in 2017 the first litter of smooth-coated otters in continental Europe, seven pups at once. The nocturnal cave section was built for pangolins after Egyptian fruit bats were removed in 2020.
