Excavations have brought to light many important findings that this land has held for centuries. These findings show the special place the area (and all the towns and settlements within it) has shed ever since the Stone Age.

    The ruins of the acropolis of ancient Methana, discovered on the hill of Paleokastron near Vathi, transfers the awe-filled visitor many centuries back. The abutting archaeological findings indicate that the area has been inhabited continuously since the Neolithic Era (5,000 BC) while remains of ancient houses from the sunken city of Methana still remain on the bed of the sea.

    We can still find seaside hills with the remains of classic and ancient forts on Nisaki Agii Anargiri; Cyclopean and medieval walls in the location of Magoula west of Agios Nikolaos Paleon Loutron; and the ruins of a classic fort with the remains of an ancient temple within its walls on the hill of Ogas near the beach of Kipseli.

    We also find interesting monuments on the plateau of "Throni" where there is a well-preserved, 4th century tower and the ruins of a 3rd century oil-mill; on the summit of Helona where we see round and rectangular water basins which are believed to date back to the Byzantine times; and in the location of Agios Nikolaos where we find the remains of Roman building constructed to facilitate the use of the spas. This is believed to be the building that Pafsanias refers to in his writings.

    There is also the impressive, medieval "castle of Fabiero", with the four small towers in its corners, which is found in the Methana Steno. North of the fort remains a large part of the protective wall, which, according to the historian Thoukididis, was built by Athenians during the Peloponessian war (425 BC).

    A site of great archaeological importance is the hill of Agios Constadinos and Eleni where a prehistoric settlement of the Mycenean Era (14th and 13th century BC) has been unearthed. These findings have brought to light many new and important facts and have added greatly to our knowledge of the art and religion of the Mycenaean period. Findings in one of the buildings of the settlement indicate that it was a place of worship of a prehistoric deity, possibly Posidon.

    Scattered throughout the Peninsula, we find little churches as well as Byzantine and modern churches which add their own "colour" to the historic wealth of the picturesque Peninsula.
