That the site had long held ritual significance in the area is shown by the fact that the church stands right next to a large burial mound. The earliest churches were often placed close to such sites, which had previously served as gathering places for pagan worship.
According to a local tradition, the predecessor of the present church is instead said to have been built as late as 1738, replacing the medieval church, but is said to have been of such poor quality and so draughty that one day the altarpiece was found blown down onto the floor.
What is clear is that both the church and a large part of its furnishings date from the same period, giving a somewhat unusual, undisturbed neoclassical church setting. The nave is large and light. There have not been many major changes to Krokstad church since 1863, but in connection with the interior restoration of 1993, the church was also altered somewhat, with a conversation room and cloakroom built under the gallery. The wooden font is from the 17th century and bears the inscription: "Then ther troor och blifuer Döpt, han skall warda Salig: Men then ther icke troor: han skall warda fördömd. Marc 16 ver 16."
The organ is from 1884, with organ works from Tostareds orgelfabrik from 1993.
In the tower there are two bells, the smaller originally from 1614 (recast in 1900 and 1946) and the larger from 1844 (recast in 1946).
In 1917, in connection with the celebration of the 400th anniversary of the Reformation, the church was visited by King Gustav V and Queen Victoria, who, in memory of the occasion, signed their names in the church Bible from 1917.
