I have a museum of sorts in the Hall of the Lunar Champion (free if you do the Season of the Dragon quest line), and about 5 (I think?) of the Sixth House Ritual Tables you can get antiquity leads for if you spend enough time in Vvardenfell. That house (including the Lion's Cradle and Halls of Colossus annexes) is packed with items I've picked up through excavations and other activities. Those tables are quite nice, by the way.
