A wall extending along Butte Garden and headed by 15 animal sculptures, bearing feelings on their face and appearing as if they are trying to escape, designed by William Burgess in 1866 and built in 1890 AD and painted in natural colors, although the paintwork on the statues has been removed. The animals that head the fence are: a wolf, a lioness, a seal, two lions, a lynx, a bear, a baboon, a hyena, a swan, an anteater, a raccoon, a leopard, a vulture, and a beaver. .
