All of them (a dozen large ones and hundreds of small ones) were built with roughly cut stone bounded with a thick layer of malter on the outside. Large churches are longitudinal with one or three naves like Church of Holy Salvation () at the spring of the river Cetina, built in the 9th century, along with the Church of Saint Cross in Nin. The largest and most complicated central based church from the 9th century is dedicated to Saint Donatus in Zadar.
