待賢門（たいけんもん）は、平安京大内裏の外郭十二門のひとつで、左衛門府が警固を担当しました。延暦13年（794年）、宮城経営のとき播磨国が造営し、建部氏がこれを監したことがその名称の由来です。当初は「建部門」といいました。東面の中央にあるため中御門とも呼ばれました。弘仁9年（818年）、額を改め、嵯峨天皇の筆額を掲げました。
Taikenmon was one of the twelve outer gates of the Heian-kyo palace, with the Saemonfu (Left Guard Office) responsible for its security. In the 13th year of Enryaku (794), during the construction of the imperial palace, Harima Province built the gate, and it was supervised by the Takebe clan, which is the origin of its name. Initially, it was called "Takebe Gate." Because it was located in the center of the eastern side, it was also called Nakamikado. In the 9th year of Konin (818), the plaque was renewed, and an inscription by Emperor Saga was displayed.
