Blaise estate is managed by Bristol City Council.
There are many caves on the Estate, one of the estate's man made caves Butcher's Cave, given its name because of the red tinge to the stones inside, resembling hanging joints of meat. The other one is Robber's cave constructed with large rustic local limestone blocks over shallow excavated hole to serve as a feature for carriage drives to the castle.
Local legend suggests that the footprint was created in a fit of rage by the Giant Goram. In fact it is an area of horizontally bedded carboniferous limestone, exposed through glaciation some 10,000 years ago. The cavities are created where rock has been dissolved through the passage of water down vertical joints.
