Burke argues that the structures are not altars, but more like thrones, since some have armrests associated with the top step. He also points out that there is no evidence of sacrifices: "Similar monuments—which have been found throughout Phrygia at sites such as Midas City and Kalehisar—were called “altars” by W. Ramsay. The term “altar” has unfortunately stuck. Many scholars agree that the term should be abandoned, for there is no evidence of the burning, pouring, or offerings to a divinity that would be expected if these were in fact altars...The site of Dümrek preserves the greatest number of such monuments from any known site in the region of Phrygia. The first throne has six steps leading to a seat with armrests and a crescent–shaped back support. The most remarkable discovery of our work in 1999 was an even larger stepped throne on a ridge just to the east of the first example. A massive carved boulder with eight steps leading to a seat complete with armrests had tumbled at some point in the past..."
