 In 1454 work started on a church tower, designed by Andries I Keldermans in the Brabantine Gothic style.It was planned to be, according to different sources, either 130 metres or 204 metres tall (the latter would have made it the tallest church tower in the world by far).The work was continued by his relatives Antoon I Keldermans and Rombout II Keldermans.
