The Castle Town of Monemvasia is one of the most impressive places in Greece. Located on the south eastern side of the Peloponnese Peninsula, it was entirely carved on the back side of a sea rock in the Medieval times. This huge sea rock is not visible from the mainland, so that the locals could avoid enemy attacks. Originally the only way to reach Monemvasia was by boat, now a paved pathway connects the castle entrance to the mainland.
