In 1975 reconstruction started, simplifying the building's original design and demolishing the northern wing, the 'Denkmalskirche' – Memorial Church. In 1980 the baptistery and wedding church was reopened for services. The restoration of the nave was begun in 1984. On 6 June 1993 the nave was reinaugurated in an event attended by Federal Chancellor Helmut Kohl and televised nationwide in Germany.
