Sales on Cardiff Castle Grounds are mostly flats, and every recorded sale is in one building, Blackweir Cottages. Sales here are sparse and mostly older — the last recorded sale was in 2019, so today's values are best judged from the wider CF10 figures below. Recent sales are too thin to call a trend for the street itself; CF10 prices as a whole have been rising. With 3 sales across 2 homes since 2003, homes here come to market only rarely.
