Wendelin was buried in his cell, and a chapel was built over the grave and the small town of
Sankt Wendel grew up nearby. The saint's intercession was considered powerful in times of pestilence and contagious diseases among cattle. When in 1320 a pestilence was checked through the intercession of the saint,
Baldwin, Archbishop of Trier had the chapel rebuilt. Baldwin's successor,
Bohemond II, built the present beautiful
Gothic church, dedicated in 1360, to which the saint's
relics were transferred. Since 1506 they have rested in a stone
sarcophagus. and is still venerated in Germany, Austria, Switzerland and
South Africa. Saint Wendelin's feast is observed in the Diocese of Trier on 22 October, but in the
Roman Martyrology on 21 October. St Wendelin is also celebrated in Hungary. Two statues celebrating Saint Wendelin and Saint Florian are in a small square in Zalavar village. They sit on separate similar plinths next to each other. (This arrangement and the style of the statues appears to be in the period 1900-1930). The statues are not outside the village churches. Many villages in west Hungary have two Christian churches, one Catholic and the other Protestant.) Before 1920, German was the dominant language in hundreds of villages in Hungary, although Zalavar appears to not be in the main German speaking areas. A Zalavar monument listing people who died in both World Wars has two or three names of German origin. Zalavar cemetery has very few graves displaying names of German origin. At the oldest section of the cemetery furthest from the road most graves have no headstone. Sacred Heart Church in
Perkinsville, New York holds a relic of Wendelin. In 2017, a German film crew visited the hamlet while making a documentary about the saint. == Iconography ==
