The present building dates from the 1200s, or possibly a little earlier, and appears to have replaced an older 12th-century church with an apse, traces of which survive as foundation stones in the east tower. The result is a so-called 'cloven-gable' church, combining a west tower, nave, chancel with a south portal, and an east tower retaining the earlier apse. Researchers believe the chancel and nave may once have had an additional storey, and a small unexplained chamber survives in the roof space. The west tower was likely demolished in the 1500s, after which the nave walls were lowered, the vaulting removed, and a timber roof on wooden columns installed instead; some scholars even question whether the church ever had two towers standing at once.
The earliest known reference to a church at Ramdala is indirect: a papal letter issued in Avignon in 1320 mentioning a provost of Ramdala. Who commissioned the original church is uncertain, though its isolated hilltop position, away from the historic village core, suggests it was built as a private estate church rather than a village one. One theory links it to the Premonstratensian monastery at Vä, which held land in the parish, gifted by a Danish bishop in 1182. If correct, this would mark Ramdala as the most richly built medieval church in the district of Östra Härad, though the connection remains speculative.
Inside, the barrel-vaulted nave leads to an apsidal chancel, with a sacristy tucked behind a screen wall in the apse. A triumphal crucifix hangs above the low chancel arch. Near a window on the south wall is a well-preserved painting of the sun, moon, cross and the name of Jesus, dated 1634 and rediscovered during restoration work in 1946. The enclosed box pews and west gallery both date from the 1600s.
The altarpiece, from 1624, is arranged in an architectural framework centred on the Last Supper, with inscribed panels bearing the words of the Eucharist in Danish and a small depiction of Christ's baptism above. The font and its canopy also date from the 17th century. The pulpit, carved, painted and gilded, was completed in 1637 and is said to have been a gift from King Christian IV of Denmark; its six-sided body is divided into five panels with reliefs drawn from the Book of Revelation. A memorial plaque on the chancel wall commemorates an admiralty superintendent who died in 1717.
The church's organ has a layered history: an 1860s instrument by a local builder was replaced in 1924, and again in 1969 by the current mechanical organ built by Olof Hammarberg of Gothenburg, which reuses the older organ case.
