Stonecross, David F. Nalle's free Celtic gothic font from 1997, leans into an insular manuscript mood with a heavy, carved S and sharp wedge cuts that feel half chisel, half pen. The lettering looks ancient rather than fussy, with broad curves, pointed turns, and a compact weight that gives it a stone-marked, heraldic presence.
That makes Stonecross a natural fit for book covers, pub signs, festival posters, game title cards, and chapter openers where a free font needs a medieval or Celtic note without becoming ornamental clutter. It also works well for monograms and short headline words, because the forms carry plenty of period character even in a single letter.
