Croydon, this is my town, not from birth, far from it, we moved in to our dream home, our retirement home the day before Christmas Day in 2017. Since then I have discovered more and more to this area that I really love, so I'm here for a long time now, well, I hope so anyway 
I am placing a series of cache in and around the area to highlight the parks, walkways and places of interest in this part of Melbourne, I hope you enjoy your visit.
Croydon History
From the mid-1880s Croydon started to develop and Mr James Hewish built his home and several other business ventures, including a general store, news agency, butchers’ shop and hotel, and planted various orchard trees. The Post Office opened on 1 December 1883 after the railway line was established. Nelson's Hill Post Office opened nearby in 1902 and was renamed Burnt Bridge in 1979.
