This impressive church has a 64.5 m high tower overlooking the town. After a disastrous fire in 1862, when the old Oswald Church burned to the ground, Eibenstock's parish church was built from 1864 - 1868 after the architectural design of Oskar Sommer as a three-bay neo-Romanesque hall church. It is the largest church of its kind in the administrative district of Chemnitz, and one of the most distinguished in Saxony. A life-sized crucifix from the 16th century was saved from the flames of the old burning church, as well as the only image in Saxony of the Holy Oswald, a wooden sculpture from the period around 1520. Also noteworthy are the historical Kreutzbach organ, the three bells in the tower that together weigh 63 centner (3,150 kg), as well as the mechanical tower clock from the Carlsfeld watch factory.

Hans Schnorr from Schneeberg, the owner of a mine and a forge, founded this church for the mental and spiritual well-being of his employees. It was built from 1684 - 1688, designed in the Baroque style by Wolf Caspar von Klengel. The Trinity church is the oldest central semi-dome (conch) architecture in Saxony and became a model for other conch buildings, like the Frauenkirche church in Dresden or the Rundkirche church in Seiffen.

The village church, inaugurated in 1617, replaced a small wooden church at the same place. The massive stone tower was built from 1692 to 1700. It is completed by a baroque hood with a slim lantern turret. The altar room is dominated by a large baroque crucifix. At festive times, two large pewter chandeliers donated in 1678 commemorate the mining past of the village. Traditionally, every year on Thanksgiving, the church is lovingly adorned with flowers and fruits.
