Tjärby kyrka

A medieval church, possibly dating from the 13th century, once stood on this site. Built of stone and brick, it had a rectangular nave, a narrower straight-ended chancel, a porch to the south and a timber tower to the west, with the interior later fitted with Gothic-style vaulting. This older building was demolished in 1906 to make way for the present church, though items considered of antiquarian value were preserved and moved into the new building.

The current church was constructed in natural stone and brick in 1906–1907 to designs by the architect Erik Lallerstedt, and is noted as the only church in the diocese built consistently in the Art Nouveau (Jugendstil) style. It comprises a rectangular nave, a narrower chancel with a sacristy extension to the north, and a west tower housing the main entrance. The grey-plastered facades sit on a high rusticated stone base, with buttressed walls, monumental stone steps leading to the entrance, and windows and doorways picked out in grey stone and red glazed brick beneath a steeply pitched, slate-covered roof. Galleries, pews and the altar rail in dark-stained wood survive from the time of construction, though the interior was altered in 1935 under Harald Wadsjö and again in a 1972 restoration, when the walls and ceiling were painted white.

Among the older furnishings rescued from the medieval church is a font carved from sandstone, considered one of the most remarkable in Halland and dated to the latter part of the twelfth century. It is thought to be the work of a stonemason trained in England. Only the square-shaped basin survives today, its top having been lost and later replaced in cement in 1937; the sides are decorated with figures in relief.

Other notable furnishings include an oak pulpit from the 1590s carved with figures of the four evangelists, and an altarpiece in oak thought to be of similar date. A triumphal crucifix, dated to the middle or latter part of the fifteenth century, hangs high in the chancel arch between the nave and choir. An iron-clad door from the fifteenth century, once part of the old church's porch, has also been preserved.

The church bears two bells: the smaller was recast in 1747 in Malmö, while the larger was cast in 1906 by a Gothenburg bell foundry, replacing earlier bells including one cast in 1627 that was said to have a poor tone by the time it was retired. The church's mechanical organ, built in the mid-1960s by a Danish organ workshop, has fourteen stops across two manuals and pedal, and was renovated in the 1990s.
