Kefermarkt Altarpiece, Gothic triptych in Kefermarkt, Austria

The Kefermarkt Altarpiece is a limewood winged altarpiece in the parish church of Kefermarkt, Upper Austria. Its central shrine holds three over-life-size statues: Saint Wolfgang (2.20 m) in bishop's robes and mitre, flanked by Saints Peter and Christopher. The carved structure rises 13.5 m and is 6.3 m wide, with 79 figures, two busts, and a dragon at Saint George's feet.

Christoph von Zelking, lord of Schloss Weinberg and adviser to Emperor Frederick III, had the church built between 1470 and 1476 and secured payment for the altarpiece in his will of 28 October 1490, endowing it with 400 gulden and eight years' income from his Wachau vineyards. He died in 1491 before it was installed; a receipt from 1497 records the final payment. After the Zelkings turned Protestant in 1558 the church was neglected and closed in 1629, reopening in 1667 under the Jesuits, who had the wings fixed and the superstructure enlarged around 1670.

The altarpiece's wings show scenes from the life of Mary, and the shrine is watched over by Saints George and Florian, mounted on the wings in 1684. The church was a pilgrimage site until about 1545, when the Reformation halted it; regular services resumed only in 1667 under the Jesuits. The altarpiece is still the parish church's high altar.

The altarpiece fills the choir of the parish church of Kefermarkt, where Christoph von Zelking is buried; the church was closed in 1629 and only reopened in 1667. Because the work is 13.8 m high and 6.17 m wide, the full superstructure is best seen from the back of the nave, while the three shrine figures are viewed up close.

During the Reformation the neglected altar was used for target practice: shotgun pellets later collected from the carved superstructure show that birds were shot at inside the church. The altarpiece was also whitewashed in the late 18th century, and only fragments of its original paint and gilding survive.
