Let us go back to 794, the thirteenth year of the Enryaku era. Emperor Kanmu was building the new capital of Heian-kyo, and beside the great imperial palace compound he had a garden laid out for the court. The name tells you why this spot was chosen: clear spring water always welled up here, so it was called Shinsen-en, the garden of the sacred spring. The original garden was far larger than the grounds you can walk today. It stretched four blocks north to south and two blocks east to west, which is about 500 meters by 250 meters. Its borders were the great avenues of the new city: Nijo Avenue to the north, Sanjo Avenue to the south, Mibu Avenue to the west and Omiya Avenue to the east. Inside, there was a large pond with an island called Nakajima in the middle. Around it stood grand pavilions, including one named Kanrinkaku and a fishing pavilion that stood out over the water. Picture the court strolling and boating here, in a garden designed to be the pleasure ground of the emperor himself.
