Barn (The Day of the Doctor)
For the Doctor, a barn that stood for many years had a particular significance, with four of his incarnations visiting it. Rassilon states that its in the Drylands where no one anyone cares about lives. The Capitol is shown to be nearby.
During the First Doctor's childhood, he would retreat to the barn to cry so that the other children wouldn't hear him. On one such occasion, Clara Oswald used telepathic circuits to land the Doctor's TARDIS in the barn and comfort the Doctor, telling him the story of how he would return to the barn one day and that he should use fear to his advantage. (TV: Listen)
The War Doctor returned to the barn, bringing with him the Moment, which he intended to use to destroy Gallifrey, the Time Lords and the Daleks. However, the Moment opened a time fissure leading to his future to show him the consequences of his actions.
The War Doctor returned from the future with the Moment ready to detonate. Soon after his arrival, the Tenth Doctor, the Eleventh Doctor and a younger version of Clara Oswald arrived to assist him in Gallifrey's destruction. However, the Moment showed them the direct consequences of their actions and the Eleventh Doctor decided to alter their plan. (TV: The Day of the Doctor)
After returning to Gallifrey, the Doctor returned to the barn and went into the loft where he slept as a child. A woman came in yelling at him that the things in the barn were for "the boys", but upon recognizing him, told the Doctor that he would be killed for coming back to Gallifrey. The Doctor then calmly ate soup outside surrounded by Time Lords of all ages when a military ship arrived and demanded his surrender. The Doctor simply drew a line in the sand and returned to his soup. As the Doctor reclined on his old bed, Rassilon sent troops to get him but the Doctor merely spared them a glance before returning to the barn. When the High Council arrived, the Doctor did the same with them. It wasn't until Rassilon himself came to the barn that the Doctor engaged with anyone. Rassilon tells the Doctor that there's no witnesses there and when the Doctor refuses to cooperate, has a firing squad shoot the Doctor. The squad purposefully misses out of respect for the Doctor, instead shooting in a circle on the barn wall. The squad joins the Doctor by the barn, siding with him and when military ships arrive, they side with him as well. After the General sides with the Doctor, Rassilon is overthrown and exiled from Gallifrey. (TV: Hell Bent)
