In 1570 The squire Jacob Rosenkrantz had the southern nave build for the residents of Thurø. They got their own church in 1640. Until then they had to travel to either Bregninge or Svendborg for service. Along with the southern nave a porch and a small chapel was made on the northside. Under the chapel was made a crypt for the residents of Kjearstrup only.

In 1750 Niels Juel expands the northern chapel to a tomb for the Juel and Juel-Brockendorff family. I the 1793 Frederik Juel puts an balcony on the tower and the towers is remade with newer bricks. Later, in 1883, the tower got a spire. This is also the year where the chancel is rebuild and the outer walls of the church is covered with red bricks. In teh 1940'ties the counsil of the church put the suggestion that to church should be plastered with whitewash. They wanted the outside to look as the inside. This was strongly rejected. In 1998 the northern chapel was opened for the public but is blocked by a steel fence.

Bregninge church, sanctified to sct. Andreas, was build in the 11th century of raw boulder, but it is believed that here stood a wooden church earlier. The foundation is in cut granite. If one takes a look at the shape of the windows, the roman architecture style of the church is seen. As the ceiling looks late gothic is because the old flat raftered ceiling was removed between 1500-1525 and the fashion in architecture at that time was this late gothic style with the pointed arches and vaults.

The church had from the beginning only a nave and a chancel, but at the same time the ceiling was replaced the church wa expanded with a tower build with bricks and a bell from the Kjearstrup estate.
