The patron of Strongoli is Our Lady of Grace, celebrated on 15 August in the Church of Santa Maria delle Grazie.
Deeply felt by the population is also the devotion to the Blessed Virgin of Vergadoro, protector of sailors, fields and farmers, celebrated every year in May, on the Sunday coinciding with the Ascension of the Lord. The feast begins ten days earlier with a night prayer vigil, known as «la nottata». The town also holds the Collegiate Church of Santi Pietro e Paolo and the Torre Limara.
