The Museum of Science and Industry in Chicago recently completed a 9-month conservation of its Fairy Castle, an elaborate dollhouse created by silent film star Colleen Moore and donated to the museum in 1949.

The Fairy Castle was built with a plumbing and electrical system — the bathtubs have real running water, the chandeliers light — and filled with collected and custom made exquisite objects, like tiny gold plates and crystal glasses, miniature needlepoint tapestries, the smallest Bible in the world, actual ancient Egyptian mini-statues, and a sliver of the true cross, given to Moore's friend Clare Boothe Luce by the pope. The castle cost $500,000 to create in 1935, equivalent to over $8 million in today's dollars.

Above, you can watch a time-lapse video of the castle being put back together by the conservation team. It shows the objects being placed back into the rooms in accordance with the original intention: to give the impression "that a fairy had been there but left just moments ago."
