The island was explored in 1906–07 by Richard Seager and partially documented by Halvor Bagge in ink and watercolors based on photographs (University Museum, University of Pennsylvania, 1910), and more minutely examined in 1984–92 by Philip P.

Archaeological materials in this seaport, sited above its harbor, to which it was connected by cliffside stairs, span the period from the end of the Neolithic in the 4th millennium to the
