Suzakumon Gate of the Heijo-Kyu Palace was restored in 1997 with a two-story structure, double roofs and a life-sized goken sanko (a gate where three of the five spaces between its columns are used as entrances); the restorations were based on gates that remain in temples in Nara prefecture (Heijo-Kyu palace ruin) and findings in archeological studies.
