I visited this tentative WHS in November 2014. It's a fine cathedral like many others on the list already and this might make it to the list in 2015. We'll wait and see. The highlight of my trip were the works of the Naumburg master. The film displayed on the upper floor above the ticket booth is really worthwhile viewing to get a detailed overview of the Naumburg master's works and a comparison with other cathedrals and churches in Europe. The combined ticket costs 6 to 8.50 euros + 2 euros for photography which is quite expensive especially by German WHS standards.
