Gallifrey Falls No More

 was a Gallifreyan landscape painting and stasis cube, depicting Gallifrey in the final days of the Last Great Time War. The painting specifically depicted the Fall of Arcadia on the last day of the Time War. There were believed to be two conflicting titles of the painting: No More, or Gallifrey Falls. However, according to the curator of the National Gallery, the painting's full title was actually Gallifrey Falls No More. The Eleventh Doctor believed it to depict the Fall of Arcadia a day before he used The Moment to destroy the Time Lords and the Daleks. (TV: The Day of the Doctor)

History
It was acquired under unknown circumstances by either Elizabeth I for the Under-Gallery of the National Gallery, or else by one of the Under-Gallery's curators. Elizabeth I left instructions that the painting be presented to the Doctor should any problems arise in the Under-Gallery.

In 2013, the group of Zygons who had been hiding in other Time Lord paintings in the Under-Gallery awoke, triggering a response from UNIT (though they were unaware of the Zygons' presence). Kate Stewart presented the painting to the Eleventh Doctor and Clara Oswald to secure their assistance. Immediately after the group entered the Under-Gallery proper, UNIT technician McGillop received a call from the Doctor instructing him to move the painting to the Black Archive. Unknown to everyone involved, the Doctor and Clara, along with the Tenth Doctor and the War Doctor, had hidden inside the painting to gain access to the Black Archive to stop the Zygons. All three Doctors combined the power of their own sonic screwdriver to create a sonic shield which blasted a Dalek through the glass of the painting. The Doctors emerged from the painting inside the Black Archive, just in time to resolve the situation with the Zygons.

The painting was soon restored to its proper location in the National Gallery. The Doctors and Clara had tea in front of the painting, musing on whether they had been successful in saving Gallifrey. After the Tenth and War Doctors had returned to their own places in time, the curator of the National Gallery greeted the Eleventh Doctor. The curator explained that the painting's full title was Gallifrey Falls No More, and heavily implied that it in fact depicted the Fall of Arcadia at the moment the Doctors were successful in freezing Gallifrey and hiding it in a pocket universe. The Doctor was energized by this news, he resolved to seek out his home and restore it at last. (TV: The Day of the Doctor)
