Did you know that in one of the ancient languages of Persia, the word for garden, “pairi-daeza”, evolved into “paradise” ? Just one of the discoveries unveiled by this enchanting exhibition which traces the epic of fantastic gardens from those of Babylon to the recent Al-Azhar Park in Cairo. For the event’s duration, the esplanade of the Arab World Institute will play host to a fabulous ephemeral garden entrusted to landscaper Michel Péna. This devoted fan of the world of plants offers his contemporary interpretation of the gardens of the East. A playful and sensorial invitation to stroll through alleys of roses, jasmin, orange and palm trees. From April 19th to September 25th. Institut du Monde Arabe, 1 rue des Fossés Saint-Bernard, Paris 5 (01 40 51 38 38).
