The patron of Letino is San Giovanni Battista (Saint John the Baptist), celebrated on 29 August; the municipality holds the church of San Giovanni Battista.
The tradition of wearing the costume is still celebrated today, above all in August, staging a kind of comedy that shows what young men had to do to win a girl of the village as a bride. The municipality also holds Santa Maria a Castello, the Cappella Santa Maria dell'Arco and Monte Ruzzo.
