Borovci is a village near Metković in the Kula Norinska municipality with a population of 29 (2021 census).

It is surrounded by hills, Tikvina and Gradina from the northeast, and Rujnica from the southeast.

[3]Near today's village of Vratar is a five-sided medieval fort with two towers, on Gradina, at an altitude of 97 metres (318 ft).

During works on the church in 1997 remains of the first phase's wallsm built in a romanesque style, were found.

In 1779 bishop Fabijan Blašković ordered the church to be expanded to meet the needs of the increasing number of inhabitants.

With the monetary help of Croatian Americans from Borovci, monk Mijo Ivandić expanded the chapel and dedicated it to the Virgin Mary.
