The fact that Conrad was a senior church official (de:Domherr, a type of canon) at both Mainz and Speyer Cathedrals may have been relevant to both request and grant.

In addition to the monastery and church, the parishes of Eppingen and Hessloch [Note 1] were given to the Carmelites for their financial security.

In 1511, an extension was built on the south wall of the nave of the church; in 1515, this became St Anne's Chapel, dedicated to the mother of Saint Mary.

The Lords of Hirschhorn seem later to have converted to Lutheranism, because between 1522 and 1529 they installed a Protestant pastor in the church, and demanded that the Carmelites not wear the monkly habits of their order.

In 1530, the Carmelites were taken under the protection of Emperor Charles V. They were tolerated by the Hirschhorns until 1543, when Hans IX dissolved the monastery.

[Note 2] The Hirschhorns ignored those decisions, and demonstrated their power in around 1590 by replacing the altar in St Anne's Chapel with a family tomb.

After his death, Hirschhorn fell under the rule of the Archbishop-Elector of Mainz, who re-established the monastery as a centre for re-catholicisation of the neighbouring communities and parishes.

It originally divided the body of the church from the chancel (i.e. it served as a rood screen), but was moved to its present location no later than 1618.
