By the middle of the century medieval ruined castles had become fashionable once again. They were considered an interesting counterpoint to the now conventional Palladian classical architecture, and a way of giving a degree of medieval allure to their new owners. Historian Oliver Creighton suggests that the ideal image of a castle by the 1750s included "broken, soft silhouettes and decayed, rough appearance". In some cases the countryside surrounding existing castles was remodelled to highlight the ruins, as at Henderskelfe Castle, or at "Capability" Brown's reworking of Wardour Castle. Alternatively, ruins might be repaired and reinforced to present a more suitable appearance, as at Harewood Castle. In other cases mottes, such as that at Groby Castle, were reused as the bases for dramatic follies, or alternatively entirely new castle follies could be created; either from scratch or by reusing original stonework, as occurred during the building of Conygar Tower for which various parts of Dunster Castle were cannibalised.
