I have not completed a lot of research on the Gardens as yet, but have come across some amazing pictures so have started this post to share what I currently have found. The earliest photo is the one below, which I think is simply magical – I just wish I could find a better copy!
“This pavilion was constructed in 1924 to the design of honary architect Edward Twentyman. The scheme derives from the Tholos of Delphi. It is a circular Doric building with rather attenuated columns, more Tuscan or Roman Doric than Greek Doric. There are 8 plain unfluted shafts with five panels of metopes between. The dividing triglyphs have two vertical shafts and are complete with guttae, all slightly brittle and thin in execution. There is a plain cornice above it and a dome in metal sheeting. The pavilion base is a solid drum and there is a high flight of stairs rising to it. An early photograph of the building shows that the base was originally rusticated and the rough cast finish a later alteration. There was originally an iron fence around the structure.” (North Fitzroy Conservation Study, 1978). (Glossary)
