The Dommuseum is a treasure trove of sacred art. A visit whisks you past a cabinet of Renaissance curiosities crammed with crystals, coral and oddities such as armadillos and pufferfish, through rooms showcasing gem-encrusted monstrances, stained glass and altarpieces, and into the Long Gallery , which is graced with 17th- and 18th-century paintings, including Paul Troger’s chiaroscuro Christ and Nicodemus (1739).
From the organ gallery, you get close-ups of the organ Mozart played and a bird’s-eye view of the Dom’s nave.
