 Master Martin, who was a church builder from Burgundy and Champagne, as shown by details of his ornamentation, also knew the design idiom of Cologne and Trier cathedral construction workshops, was responsible for the overall design.This included at first a long choir like that of St Vitus' Church, Mönchengladbach.Afterwards this concept was given up under the management of Master Martin and a hall church inspired by St. Elizabeth's Church, Marburg (begun 1235) was built, which was built over the outer crypt.
