The church was constructed in 1937 to designs by the architect Johannes Dahl. It is a modest building with a tower on its western side and an attached porch beside the tower. The tall, steep gable roof and the tower are both covered with black-painted sheet metal, giving the small church a distinctive, dark-roofed silhouette against the surrounding landscape.
Inside, the focal point is the altar at the east wall, above which hangs a wooden crucifix carved by Eva Spångberg. This is the church's most notable piece of decorative art, and offers visitors a simple, quiet devotional image typical of many rural Swedish churches from the early twentieth century.
The organ was built in 1954 by Olof Hammarberg of Gothenburg and is a mechanical instrument. While modest in scale, it reflects the mid-century craftsmanship applied even to small parish churches of this size.
Örserums kyrka serves as the parish church for Gränna församling within the Diocese of Växjö, though it is managed by a local chapel foundation rather than directly by the parish administration, a slightly unusual arrangement worth noting for anyone curious about its upkeep.
