Gate of Urg, is a gate in Gringotts, The Wizarding Bank, that leads to Vaults 100-799 and 900-1000. Gates 900-1000 are a new addition to Gringotts, which means they are not as secured as Gates 800-899 This gate is only accesible by goblin because it is the most secured section in Gringotts. The gate was added in 2005 to add more security to those gates that people wanted to keep in complete safety. The gate is named after Urg the Unclean. Urg was an activist in the Goblin Rebellions. It was meant to show the Goblin's Pride.
After the Battle of Hogwarts, in 1998, Death Eaters lost control of the Ministry hereby Gringotts. The goblins were furious at wizards for killing so many of their own kind. Gringotts officially closed down for about a month, but reopened after Kingsley Shackelbolt settled things for them. The goblins after reopening decided they would never be robbed again, so they set up more security. The Gate of Urg has the average protection .(History made up by editor. Do not take seriously).
Gate of Urg has two wizard guards on each side who check that the goblin escorting you is not under the Imperius Curse or is a Traitor to the Bank. Once on the Mine Cart the customer will go through the Thief's Downfall.
