Small hall church of St. Trojice from the 15th century, a protected cultural monument, is located on Lokvina Square in Kastav. The interior, in the sanctuary of which there are frescoes with old Glagolitic inscriptions, proved to be an inspiring and demanding exhibition space for artists of all media.
It has been used as a gallery space for many years, and since 2014 it has been used as a city exhibition space. The activity and program are directly financed by the City of Kastav.
