The patron of Terricciola is Saint Donatus, celebrated on 7 August in the Church of San Donato.
The calendar of feasts is rich: in April, the spring feast at La Rosa; in May, the strawberry festival and, at Morrona, open wineries and a feast of cheer for the national Cantine Aperte day. In July, archaeology nights are held and, at the Podernovo estate, summer Thursdays with Musica in cantina. The town also holds the Abbey and Church of Santa Maria a Morrona.
