A timber chapel was first built at Öljehult in 1754, when the distance to Bräkne-Hoby church proved too great for local worshippers. As the population grew, this early chapel became too small, and it was demolished and rebuilt on a larger scale between 1840 and 1842, departing from the official architectural office's original plans. Öljehult became its own parish in 1859, at which point the chapel formally became a church.
The building is designed in a Neoclassical style, with an unusual eight-sided nave, a closing chancel wall, a sacristy behind, and a porch with a bell tower. It is built of horizontal timber, rendered and limewashed white. Inside, numerous windows set both low and high give the church a notable sense of light and spaciousness despite its modest ceiling height.
The chancel is dominated by an antique-inspired altar arrangement from 1884, framed by paired columns and topped with a triangle and radiating sun motif. At its centre is an altarpiece depicting Christ teaching in the temple, painted that same year by Bengt Nordenberg, an artist originally from Blekinge who completed the work in Düsseldorf. A separate oil painting near the chancel, showing the suffering Christ in an 'Ecce Homo' motif, is recorded in an old inventory as the church's former altarpiece.// The pulpit, decorated with gilded symbols, originally stood as an altar-pulpit before being moved to its current position in 1884.
The wooden font dates from 1910, the work of a local craftsman, and was later fitted with a carved candlestick added in 1981. Near one of the front pews stands a churching stool, a reminder of a now-discontinued ceremony in which women were formally reintroduced to the congregation by the priest after childbirth.
The church has had several organs. An 1883 instrument with seven stops was replaced in 1922 by a larger Walcker organ, and in 1959 a new mechanical organ with twelve stops was built by Werner Bosch of Kassel, which remains in use today.
