The Church of St. John is located in Šilovo Selo, in the vicinity of Sundjurdje. The original pre-Romanesque Church was expanded in the 15th century and a new renaissance Church of flat surfaces and much larger dimensions was built. The original Church became a presbytery.
The original Church of St. John was a single nave edifice built probably in the 11th century. The interior had a semicircular vault intersected by two girdles and divided into three aisles.The facade walls feature a rhythmical alteration of decorative lesenes and niches (four on each side of the building) that are deeper than on other buildings on Šipan, of the same period. The apse was semicircular inside and rectangular on the outside.
Fresco decoration, with inscriptions in Latin, can be found in the apse and on the South wall, indicating that once the entire interior was painted.
