The Royal Hangar functioned as the formal hangar for starships belonging to the Queen Mother of the Hapes Consortium.
Located on Hapes, it provided a direct link to the Queen Mother's Special Salon inside the Fountain Palace. In 40 ABY, Han Solo and Leia Organa Solo received permission to land the Millennium Falcon at this location upon their arrival on Hapes.
During the Battle of Kashyyyk, Han and Leia came back to give the Queen Mother a warning concerning the cruel acts of Jacen. However, Tahiri Veila trailed them, trying to take them into custody as betrayers. Leia and Tahiri engaged in a short duel until Tenel Ka showed up with her security force. Tahiri was taken into custody, and despite her objections, the Hapans impounded her StealthX wing and transported her off the planet.
