The Kačić family buildings represent a complex of traditional Dalmatian vernacular architecture. Original parts of this residential - business unit date back to the 18th century. In the courtyard there is a gustirna, which is the local name for a well, and in the eastern part of the complex there is a large olive stone mill dating from the same period when the complex was constructed. The stone mill serves as a monument to the tradition of olive oil production and the harsh life of hardworking folk from Bratuš who had lived off their land for centuries.
