At the beginning of the 14th century, Jedľové Kostoľany is mentioned in connection with the inventory of the estate of the nearby Hrušov Castle. From the forties of the 16th century, Kostoľany came under Turkish administration and remained in it until the Turks left Slovakia. The central part of the village later began to be built around the church from 1796. Gradually, settlements were established in the area, which are called "stalls" in this region. There are currently twelve of them and they are part of the Fir Kostolians. The first written mention of the church in the village comes from 1332, when there was probably a parish and a school. The church in its current form - the Classicist style - was built in 1796 on a hill above the village by Cardinal Sigismund Keglevich and is dedicated to all saints. Southeast of the village on the ridge of the hill in Cigánská dolina are the remains of a guard building from the second half of the 14th century - Živánská tower, which had an important mission in the Middle Ages. The location of the tower just above the road highlights the importance of the historic road that was controlled by the tower. To this day, its northern part is preserved, where you can see the original thickness of the masonry and the location of the windows. The tower was an accessory of Hrušov Castle and later served bandits, from where it was named "Živánska".
