As an agricultural settlement, Selca began its existence as a small part of the parish (the smallest administrative unit within the Christian Church) of Gornji Humac. Thanks to stone masonry the settlement later began to evolve rapidly, which then led to an administrative reorganisation that made Selca its own parish in 1815. Local demographics statistics show a boom in the numbers of inhabitants, going from a population of 124 in 1678 to a population of 400 in 1763. The small church which could take only 20 people was then expanded, as did the village itself with newly built houses and administrative establishments. The town slowly took the form of a well-established economic center on the east side of the Island of Brač. The first school on said side of the Island then opened its doors in 1859.
