Some of the VMS tents have a grotto-like flavor to them.
Natural bathing resorts, the thermal-bath spas, were like camping spots. I think there might be a relationship between the two ideas, tents (camping) and grottoes (bathing)---at least for some of them. Since they are scattered in different spots, I'm not sure that's true for all of them. But tents were a part of life in those days, especially for the upper "mobility" (the mobile nobles). They were always on the move protecting their territories and "putting in an appearance" for their subjects.
