ShangriLa NF Small Caps by Nick Curtis is a free Art Nouveau gothic caps font with long, tapering strokes and a slightly calligraphic sway. The letters feel theatrical rather than severe, mixing broad, black curves with pointed finishes and a few curling touches that give the alphabet a poster-era, turn-of-the-century flavor.
It works well on book covers, wine labels, boutique packaging, title cards, and short magazine cover lines where a free font can bring in period drama without looking fussy. Use it for monograms and drop caps too, since the caps have enough sweep and contrast to carry a page in just a letter or two.
