The Bratislava zoo was conceived as an intracity zoo, placed into a diverse basic local government, an urban neighborhood called Patrónka-Mlynská dolina,

through which the stream Vydrica flows, and which has a downward slope and a partly forested terrain. The original zoo was concentrated alongside this UNESCO protected river, the meanders of which are included in the project of P. Bartoš. Vydrica is positioned next to a highway, due to which the entryway and the main part of the zoo had to be moved to a different location at the beginning of the 80s. Bartoš created a plan respecting the needs of the animals and their ability to adapt to their current conditions with regard to the plan of an extension of the zoo, which happened after the construction of the highway.
