Jonathan’s age is an estimation but shell measurements documented from a photograph taken shortly after his arrival to St Helena show he was fully mature and at least 50 years old when he arrived from Seychelles in 1882 – although it is likely that he is even older.Joe Hollins began caring for Jonathan when he worked as the St Helena’s vet and, although now retired, still helps look after the tortoise.“It is such a privilege to be able to care for this magnificent animal.”To celebrate his 190th birthday, residents from across the island will be come together on Friday to honour Jonathan over three days at a birthday party at the Governor’s House.Highlights will include a display of a range of posters celebrating Jonathan’s life, bearing pictures and messages from those who have visited him over the years.An animated video and song dedicated to celebrating Jonathan’s life will premiere on Sunday, and he will be given a ‘birthday cake’ – made entirely out of his favourite healthy foods."
