新発田藩主の別邸を茶寮に変え、幕府の茶道方縣宗知（あがたそうち）を招いて造営した池泉廻遊式庭園です。庭園内の樹木は諸国の名所の種苗を取り寄せて植えたものと言われ、「心」の字をかたどった池に、美しい赤松を植えた中島を浮かべ、周りに築山をめぐらせてあります。茶寮は洗練された数寄屋造りで、夏座敷から庭園を鑑賞できるよう開放的な造りになっています。

　When it was decided to transform the Shibata feudal lord’s villa into a teahouse, Agata Sochi, who served as tea master for the Shogunate, was invited to work on the construction of this pond stroll garden. The trees in the garden are said to have been planted from seeds and seedlings obtained from famous places around the country. The pond, modeled on the Chinese character for “heart,” offers a reflection of the beautiful red cedar tree planted on the islet, and several miniature hills dot the surroundings.
The teahouse is a sophisticated pavilion built in the sukiya-zukuri style. It has an open structure for the best possible enjoyment of the garden from the tatami room in the summer.
