Triodion Caps UCS, by Vladislav V. Dorosh of Calmius Software, is a free liturgical Cyrillic caps font with a distinctly Church Slavonic feel. The letters combine broad, ceremonial forms with small crossbars, crowns, and dot-like marks that make the font feel rooted in manuscript headings and icon inscriptions rather than modern display lettering.
It fits book covers, church bulletins, museum graphics, poster titles, and packaging for heritage or monastic products, where that sacred, historical tone matters more than neutrality. As a free font, it also works well for title cards, initials, and short headings, because the caps carry so much visual ritual in just a few letters.
