El esparto de Sesma Curiosity · Sesma, Tierra Estella, Navarra Image of Sesma, not of the place itself. For generations, whole families in Sesma worked the esparto grass that grows wild within its boundaries, a trade abandoned more than eighty years ago that the town commemorates each year at the Feria de Artesparto, held on the last Sunday of April or the first Sunday of May.
