I have recently been thinking about that particular design and architecture that I used to see a child in the sixties and seventies in parks. There is little of it left and that is no surprise really as it lacked taste, delicacy, subtlety or safety. Leaving aside memorial fountains and other architecture such as war memorials, quasi-zoological displays and functional sports facilities such as bowling greens, as well as most of London as this is a county town rather than metropolitan phenonenon, I would say that it was essentially characterised by excessive floribundance, ostentatious rurality and unabashed exoticism. It was as if social classes deprived of the countryside could not be expected to recognise normal horticulture, but needed to be presented with super-horticulture, far more vegetative and floral than would ever occur in nature. The reality was also a kind of superstiumulus, with toilets and tea rooms far more rural in their reed roofs, carved gables and leaded windows than one could ever hope to see in the Cotswolds - hence the word "cottage" in gay parlance. I also recall a Guildford park where the Japanese garden (looking back now) was as overblown as willow pattern, a caricature orientalism that is quite offensive now. And how little of it survives! It did not work, was unsafe for children, was ugly, high maintenance and devoid of all authenticity. Yet when I see it relatively undisturbed (as in Grange over Sands) I regret that so little of it remains. Hazel Conway's "Public Parks" records an interesting selection and locates it historically.
