The chapel is located on the very seacoast within an area that has been known as Trojstvo (Trinity) for centuries. While part of a private property nowadays, the chapel is a small single-nave building with a stone vault and gabled roof made of stone slates. It is assumed to have been built during the 15th century. The remains of exceedingly valuable fresco decoration are preserved on the inner walls of the chapel.

The chapel was restored with minimal interventions, and its authenticity has been preserved to the greatest extent.
