The Heian Palace (平安宮, Heian-kyū) or Daidairi (大内裏) was the original imperial palace of Heian-kyō (present-day Kyoto), the capital of Japan, from 794 to 1227. The palace, which served as the imperial residence and the administrative centre of for most of the Heian period (from 794 to 1185), was located at the north-central location of the city in accordance with the Chinese models used for the design of the capital.

The palace consisted of a large rectangular walled enclosure, which contained several ceremonial and administrative buildings including the government ministries. Inside this enclosure was the separately walled residential compound of the emperor or the Inner Palace (Dairi). In addition to the emperor's living quarters, the Inner Palace contained the residences of the imperial consorts, as well as certain official and ceremonial buildings more closely linked to the person of the emperor.

The original role of the palace was to manifest the centralised government model adopted by Japan from China in the 7th century—the Daijō-kan and its subsidiary Eight Ministries. The palace was designed to provide an appropriate setting for the emperor's residence, the conduct of great affairs of state, and the accompanying ceremonies. While the residential function of the palace continued until the 12th century, the facilities built for grand state ceremonies began to fall into disuse by the 9th century. This was due to both the abandonment of several statutory ceremonies and procedures and the transfer of several remaining ceremonies into the smaller-scale setting of the Inner Palace.

From the mid-Heian period, the palace suffered several fires and other disasters. During reconstructions, emperors and some of the office functions resided outside the palace. This, along with the general loss of political power of the court, acted to further diminish the importance of the palace as the administrative centre. Finally in 1227 the palace burned down and was never rebuilt. The site was built over so that almost no trace of it remains. Knowledge of the palace is thus based on contemporary literary sources, surviving diagrams and paintings, and limited excavations conducted mainly since the late 1970s.

Location

The palace was located at the northern centre of the rectangular Heian-kyō, following the Chinese model (specifically that of the Tang dynasty capital of Chang'an) adopted already for the Heijō Palace in the earlier capital Heijō-kyō (in present-day Nara), and Nagaoka-kyō. The south-eastern corner of the Greater Palace was located in the middle of the present-day Nijō Castle. The main entrance to the palace was the gate Suzakumon (35°0′49″N 135°44′32″E / 35°0′49″N 135°44′32″E / 35.01361; 135.74222 led to each of the gates, except for the three along the northern side of the palace, which was coterminous with the northern boundary of the city itself.
