"Roarer Windspiel"

Was it a megalithic enclosure? Which importance had this enclosure at the Roarer Windspiel in Costalovara on the Renon? Was it maybe an astral temple where priests held their ceremonies and rituals in the late copper age or in the early bronze age or later in the middle bronze age sepulchres of noble families. Those questions came up in the summer 2003, after different excavations in different places in this prehistoric suspicious area.
