The hill carvings of England fall into this category by default in an uninteresting way- but OTL some, such as the Westbury Horse (a very obviously modern horse carving carved in place of what reportedly was once an ancient horse carving and also to compete with the better known Uffington Horse) are also in this category in an interesting way.
So what sort of political fights would occur if, in the early Victorian period efforts to eradicate the more obviously nude carvings (such as the
Cerne Abbas Giant) were more successful, and in the 1960s political radicals made an effort to bring them back, working only or primarily from descriptions (perhaps made more confusing by the fact that the giant's looks may have varied from century to century as recuts induced minor to major changes)? The Giant's most famous feature, after all, is its penis- and I can't think of a description which doesn't feature it prominently. Since hill carvings need to be regularly re-cut in order to keep the grass off, there's lots of potential for vicious local politics, perhaps interacting with broader national and tourist imperatives, to refight the decision of how to carve a controversial figure every year. A few years of dubious compromises and hippies heading out to mow in what they feel to be more realistically ancient elements that the local council dislikes and you could end up with a very tense situation in town.
More fun: if the Cerne Abbas controversy generates some tourism, you might find other towns rediscovering (or 'rediscovering') local pagan figures to be recut into the hillside- accuracy be damned.
