Yes, there was supposed to be a Duchess/Gay memorial. There have been promises made by numerous senior staff in recent years when it’s been highlighted by various members, including the late Gigit (zoochat friend), who like many locals, including my own nieces, donated & raised money for said memorial.
The mismanagement of this memorial and the resulting poor optics it displays, lead to more disappointment for locals.
Overall, the missing memorial is a metaphor for the decline of Torbays zoo in the last ten years (above & beyond the impact TB, Avian Flu, Brexit, Living Coasts, C19 and the cost of living crisis).
