The church's earliest surviving stonework is thought to date from the 13th century, though the present tower is a much later addition, built in the 1830s. The building follows an unusual orientation, with its chancel to the south and the tower to the north, a layout that repays a moment's attention from visitors used to more conventional east-west church plans.
Inside, Höreda kyrka holds a notable collection of medieval woodcarvings. A large oak triumphal crucifix is attributed to a workshop in Östergötland from around the mid-14th century. Older still is an oak carving of Saint Michael slaying the dragon, linked to a South Scandinavian workshop of the mid-13th century, and a limewood Madonna figure of the so-called 'Appuna type', believed to date from around 1200 — making it one of the earliest objects in the church. Later medieval works include a carved figure of Saint Barbara and an oak sculpture of Saint Birgitta, thought to have been made regionally in the mid-15th century.
Other furnishings span later centuries: a brass font dated 1660, two Florentine chasubles said to date from the 1300s, and a decorative bridal crown from 1781, once used in wedding customs and now preserved as part of the church's collection.
The church contains two organs. The gallery organ has a long and layered history, beginning with an 11-stop instrument built in 1828 by Nils Ahlstrand, subsequently enlarged and altered by several organ builders through the 19th and 20th centuries, including significant rebuilding in 1882 and later restoration work in the late 1960s that sought to recreate elements of the original tonal character. A smaller mechanical chancel organ was added in 1977, its case reportedly designed following a suggestion from a local schoolteacher and cantor.
