Located in the Systematic Sector, it was used in the past as a reservoir for watering the botanic garden. Today it serves as an important observation point for visitors who can admire the diversity of tree species in this part of the botanic garden, as well as the crown structure of deciduous and resinous trees. In June, one can admire the tulip-shaped flowers of the tulip tree (Liriodendron tulipifera) giving a unique floral display.
