Cathedral of Our Lady, Antwerp
The planned second tower never came up due to lack of funds. The cathedral has a turbulent past: damaged badly in fire in 1533, then damaged in religious wars, looted during French Revolution. When I visited the church part of the interiors was under renovation. The clock on the tower is an addition from the 18th century. Lot of changes and restorations are being done. Future generations will definitely benefit from this.
