Saint Alban's Abbey, Mainz

In 805 the Carolingian basilica was consecrated, comprising three naves, but possibly originally without the transept and the two apses.

[6] The floor plan of Schloss Johannisberg, originally built as a monastery, reflects a similar construction, because St. Alban's was its mother house.

After the destruction of the Abbey in 1552, her tombstone was transferred to Mainz Cathedral, where it can be seen today in the wall of the southern nave.

The later Archbishop of Mainz (1328–1336) Baldwin of Luxembourg fortified the abbeys of St. Alban's, St. Jakob's and St. Victor's, which at that period were located outside the town walls.

A chapel was constructed from the ruins of the church , which was in its turn severely damaged in the Thirty Years' War and completely destroyed during the siege of Mainz in 1793.

The precious sacramentary from the abbey's scriptorium is preserved in the collection of valuables in the Martinus-Bibliothek, also in Mainz.
