The patron of Castelraimondo is Saint Blaise, celebrated on 3 February in the Church of San Biagio.
The town celebrates Corpus Christi every year with a traditional flower carpet laid out during the night between Saturday and Sunday, during which local associations, including AVIS, AIDO and ADMO, compose flower carpets. The town also holds the Castello di Lanciano and the Torre di Beregna.
