It's always nice to stumble across a new portal for research and for discovering (and looking at) museum objects. My latest discovery in that regard is the portal bavarikon, which - to my and hopefully also your delight - is available in both German and English.
You can find all sorts of things there, ranging from 3D images of some special items to online exhibitions and accompanying material, such as the reconstruction of how liturgical chants may have sounded - chants that are embroidered onto the blue cope of Kunigunde, which is preserved in the museum of Bamberg Cathdral.
Have fun exploring!
