Hi Jess
We celebrated created a large-scale timeline as part of our 175th anniversary celebrations last year, which was displayed at our Cocktail Party and featured in our commemorative book. As others have mentioned, it was a significant undertaking, but with the support of our Archivist, book publisher and graphic designer, we were able to produce something that was both impactful and meaningful https://thehyphen.com.au/portfolio/st-andrews-school/.
Our biggest challenge was time, so the fact you’re already thinking about it puts you in a strong position!
