As general entry is free, no tickets are sold on-site for casual visits. Any special events or tours might have separate arrangements.
Since general access to the Sint-Vituskerk for a self-guided visit is free, there is no ticket counter or a system to purchase tickets on-site. Visitors simply walk in during designated opening hours, provided no services or private events are underway.
If the church hosts a special exhibition, concert, or a guided tour organized by a third party, there might be a fee associated with that specific event. In such cases, information about ticket purchases would typically be available through the event organizer or the church's communication channels, but it would not be for general entry to the building.
