in 1831 – Dublin Zoo opened its gates for the first time. 🦁🇮🇪
On 1 September 1831, the Zoological Gardens Dublin opened in Phoenix Park, marking the beginning of what would become one of Ireland’s best-known institutions.
The Zoo grew out of the Zoological Society of Ireland, founded on 10 May 1830 at a meeting in Dublin’s Rotunda Hospital. The Society was established by physicians, anatomists, academics and other scientists interested in the study of zoology and in creating a collection of living animals along the lines of the Zoological Society of London.
When the Zoo opened, its collection consisted of 46 mammals and 72 birds, many of them donated by London Zoo. Admission initially cost sixpence, making it largely an attraction for the more affluent.
In 1840, however, the Society introduced one-penny admission on Sundays, opening the Zoo to a much wider section of Dublin society and beginning its transformation into what became known affectionately as the “People’s Zoo.”
Dublin Zoo remains in Phoenix Park today, nearly two centuries after it first opened its gates.
