The earliest church at Torsås may have been a timber stave church built in the twelfth century, replaced in the 1200s by a stone building. That medieval church is thought to have been damaged by fire in the fifteenth century and rebuilt with thinner walls and no apse. The current church was constructed between 1777 and 1780, reusing part of the medieval walls at its south-western corner, and was consecrated in July 1780 by the Bishop of Kalmar diocese.
The church is a simple rectangular hall church with a straight-ended chancel to the east and a sacristy added on the north-east side in 1897, replacing an earlier sacristy that had stood on the south wall. Extensive works were carried out in the 1890s, including new window frames, doors, and fresh plastering and painting of the interior and exterior, overseen by local craftsmen. As the church has no tower, its bells hang in a separate freestanding bell frame nearby. Further renovation in the 1950s enlarged the sacristy and introduced the chancel arch dividing the choir from the nave.
Among the church's most notable furnishings is a German-made triumphal crucifix from the fifteenth century in the chancel, and a carved altar cabinet made in Lübeck in 1465, attributed to the artist Johannes Stenrat. The cabinet's central panel depicts a suffering Christ flanked by female saints, thought to be Saint Barbara and Saint Dorothy, with further saints shown on the hinged side doors.
The pulpit, dated to 1681, is traditionally said to have been carved by a local farmer over twelve years, although an alternative account attributes it to German craftsmanship — the true origin remains uncertain. A painting of the Resurrection by A. Stenbäck, completed in 1914 and based on a well-known composition by the Danish artist Carl Bloch, served as the altarpiece for several decades before the present arrangement was adopted.
The church's organ has a complex history, with instruments built and rebuilt across several centuries; the present mechanical organ dates from 1957, though the decorative organ case at the west gallery survives from an 1897 rebuild and remains a feature of the interior.
