The Necropolis of Piano delle Forche sits near Erice and points to the area's deep pre-medieval past. Erice is usually experienced through its stone lanes, castle views, and churches, but the burial ground reminds you that this hill has been significant through many older phases of Sicilian history.
It is a specialist stop rather than the first thing to see in town. Go if you are interested in archaeology or want to push beyond Erice's postcard medieval surface into the more fragmentary remains that explain why the site mattered for so long.
