Church of the Immaculate Conception of the Blessed Virgin Mary in Kaštel Štafilić is a perfect example of a structure that combines traditional elements and Baroque stylistic forms. It was built in 1765 by Ignacije Macanović Raguseo from Trogir. The chapel and the sacristy were added ten years later.
Conservation and restoration of the altar of the Holy Cross began in 2000, and the Museum of the Town of Kaštela was the in charge of the program until 2007. From 2007 till the end of 2017, conservation and restoration of the altar and antependium, funded entirely by the Ministry of Culture of the Republic of Croatia, was completed by the employees of the Split Department for Conservation of the Croatian Conservation Institute.
A large number of wooden altars were removed from the churches in Dalmatia during the period when marble altars were preferred. This big change was the result of an improved economic situation after the danger of attacks by the Ottoman troops ended in the 18th century. Wooden altars that were not replaced by new ones were mostly painted over several times or preserved only in fragments, with altered dimensions.
Wooden altars from the parish church in Kaštel Štafilić, like the altar of the Holy Cross from the 17th century, present a great challenge for conservation and restoration, but also a pledge to guard the successors of carved, polychromed and gilded altars. The altar is in the cult and worshiped, especially during Lent, along with its altarpiece Feast of the Cross with the three Marys. The painting on canvas, work of an unknown master, is the oldest altarpiece in a parish church, and dates back to the 18th century.
