The Day of Saint Domnius, Split's protector, takes place on the 7th May bringing together around 10 thousand pilgrims, believers and other friends of Split. The main celebration includes a procession that starts from St. Domnius cathedral, passing through Riva and finishing on Doctor Franjo Tuđman square, where a Mass is then held. Sudamja, a popular festival in honour of Saint Domnius, begins early in the morning and includes many events: from brass band concerts, klapas, the selling of traditional souvenirs, wooden butterflies and similar toys for children to wooden utensils for older people, a rowing contest in front of the waterfront and the well-known Tombula, a famous, popular game that offers players the chance of winning money.More detailes you may find here.Tourist agency Vetus Itinera, Split.
