The Church of St. Nicholas is situated on the North-Eastern part of Dubrovnik, in Prijeko, on a very important urban point and on a cliff that rose steeply above the lowland part (campus). It is also known by different names such as Ecclesia S. Nicole de Campo, appresa Doghana, Saneto Nicola de piazza or Saneto Nicola in salinize, because in the 14th century was built another Church dedicated to St. Nicholas.
The Church of St. Nicholas in Dubrovnik is mentioned around 1100 in connection with the war between Dubrovnik and the Serbian King Konstantin Bodin (reigned 1081- ca. 1099).
It's a single nave building with four bays and a dome, similar to the Church of St. Peter in Omiš. Its apse is semicircular inside and rectangular on the outside. The walls of the apse and dome were decorated with shallow semicircural niches.
In the course of time the Church was rebuilt several times. The northern lateral nave was annexed to the original pre-Romanesque church and the altar area was rebuilt. The southern side, dome and apse still have shallow decorative niches.
