Today's parish church, the Church of the Assumption was erected on the foundation of the early gothic church and was expanded and fortified in 1535. The church vestry preserved valuable liturgical vestments and several crosses of artistic value and the painting of "Mother of God and the torture of Fabian and Sebastian" of the Flemish-Venetian painter Pietera de Costera is especially valuable. 15th of August, the day of Vela Gospa (The fiesta of the Assumption) there is a fiesta in Jelsa when people from the surrounding places visit Jelsa.
On the night of Good Thursday from Jelsa starts the procession Za Križem (Procession of the Cross) towards Pitve then further on towards Vrisnik, Svirče, Vrbanj and Vrboska. After a 22 km long journey, with the first rays of morning sun the procession returns to the parent church. This unique tradition which has been going on for 500 years is on a representative UNESCO list of non-material cultural heritages of the world.
