Stone walling encloses many old gardens. The east stonewall in the Medieval Bishop’s Palace Garden in Lincoln, is Roman, the north wall is Medieval. Some mellow brick garden walls at Harrington Hall, HE Grade II, are thought to date back to Henry VII. Here a shelter with a tile roof is built into Harrington Hall’s old walling, (likely where a gateway stood previously).
Pantile-topped stone walls are a feature Lincolnshire probably date from the 17C influence of the Dutch engineers working in the Fens, re-using pantiles from demolished buildings as coping stones.
