Official websites
Where to find them
Buda Castle is not one institution but several. The Royal Palace administration runs budacastle.hu with information about St Stephen's Hall and the wider restoration projects. The Hungarian National Gallery (mng.hu) and the Budapest History Museum (btm.hu) each have their own official sites. The Castle Hill Funicular is run by BKV — bkv.hu.
What the official sites offer
Searchable online collections of every painting and artefact, often in zoomable high resolution. Exhibition calendars stretching months ahead. Research access for academics and curators. Education programmes for schools and adults. Membership and annual passes. Press, image-licensing and group-booking enquiries.
How this site differs
This site exists to make booking faster, with a clearer mobile experience, in more languages and with flexible cancellation up to 24 hours before your slot. Tickets here include the same museum admission as those bought direct. For institutional questions, research access or membership, use the official sites.
