St Charles Dark, by Studio ROP and OMEGA Labs, is a free Celtic Gothic font with a carved, medieval pull. The letters mix broad, sweeping curves with sharp hooked cuts, giving the font that old manuscript and stone-inscription mood without feeling fussy.
It fits naturally in pub branding, festival posters, album covers, book jackets, and title cards where a historic or folklore tone matters more than neutrality. As a free font, it also makes sense for short headlines, chapter openers, and monograms, since those dramatic bends and pointed joins carry plenty of character in just a few letters.
