Saiku Heian-no-mori Park recreates one of the many rectangular blocks of the Saiku Palace area. This one reconstructs three buildings used by the head of the Saikuryo, the government office of the Saiku Palace.

The left building is the Nishiwakiden, center is Seiden (main building), and right building is the Higashiwakiden. The buildings are only approximations of what they actually looked like. Only the size could be determined from pillar holes, but not the actual apperance. This is where the Saio Matsuri festival's Departure Ceremony is held.
