In 1493,the parish of Cochem was granted leave to build a new chapel in Sehl on the bank of the Moselle. There had already been a chapel in Sehl, but its whereabouts are now unknown. Financing for the new chapel was made possible by Pope Alexander VI's and Archbishop of Trier Johann II of Baden's (1456-1503)indulgence privileges. Of this chapel,the quire still stands today, filled out by the west portal built in 1915. The chapel was consecrated for God's worship to the holy abbot and local resident Antonius,the holy bishop Wolfgang (depictions of whom are to be found used as keystones together with Archbishop Johann's coat of arms) ,the Madonna,the holy bishop Ruprecht and the holy virgin Cunen. Each Tuesday and Thursday, a Mass was to be said in the chapel by the Cochem pastor, for which the chapel would yearly receive 6 Gulden and 24 Weibpfenning in Cochem currency. For that, the hay from Sehl's meadows,bordering on the chapel,was pledged. Sehlers were "half-townsmen" of Cochem without their own municipal rights, and thus Cochem town council at first spoke out against the move to bring a bell to the so-called Sehler Dom ("sehl Cathedral"). Nevertheless, the chapel later got one that was poured in 1441. It bears the inscription "AVE MARIA GRACIA PLENA DOMINUS TECUM MCCCCXXXXI" ("Hail Mary,full of grace-the Lord(is)with thee -1441"). Found here today is a "Mary Under the Cross"from the early 16th century, a gift from Dean Eckert to Saint Martin's.
