Stretching for 1,150 feet from the Hall of Prayer for Good Harvests (in the background) towards the East Gate is the Long Corridor. There are 72 rooms along this wooden colonnade with a common back wall and roof. During Imperial times, gifts and sacrifices used by the emperor during sacred rituals were ceremoniously carried through this passage on the eve of the event. Today, it is a haven for senior citizens who gather to socialize.
