We all love to visit private gardens of all shapes and sizes. In many cases we have to pay to enter whether it is for a charitable cause or purely for the benefit of topping up the owners coffers. So it may come as a surprise to find, that some of the most iconic private Italian renaissance gardens were free and public spaces right from the outset, and this unfettered access was guaranteed by the concept of the Lex hortorum or the law of gardens.
