On 13 October 1014, his relics were transferred to the Abbey of Melk by Bishop Megingard at the request of Marquis Saint Henry of Austria.
Decades later, they were taken to Hungary.
 Coleman became the object of a popular cult, and many churches and chapels in Austria, the Electorate of the Palatinate, Hungary, and Bavaria were dedicated to him.
 He is also venerated in Ireland.

A legend states that Coleman's body remained incorruptible for eighteen months, remaining undisturbed by birds and beasts.
 The scaffolding itself is said to have taken root and to have blossomed with green branches, one of which is preserved under the high altar of the Franciscan church at Stockerau.

Géza I of Hungary named one of his sons, King Coleman of Hungary, in his honor.
In the 13th century, the younger brother of King Bela IV of Hungary was named Coloman of Galicia-Lodomeria in honor of the saint.

Eventually, the relics of Saint Coleman were taken back from the Cathedral of Székesfehérvár to Melk Abbey in Austria, where they are still kept.
Many Austrian rulers made modifications to the tomb of this saint, and the actual reliquary was made in the Baroque style.
