Menelaion at Therapne**
8th – 4th cent BC
5 km southeast of Sparta

The tomb of Manelaos an Helena, Panoramio

The Menelaion, located in ancient Therapne on a hill 5 km southeast of today’s Sparta, was dedicated to Menelaus and Helen of Troy. This was a temple built on a tall base where, tradition and Pausanias hold, Menelaus and Helen were buried. Finds from excavations (inscribed shards and bronze items, as well as a stele) testify that this site was a place of worship for Menelaus and Helen. The sanctuary ruins, which survive today, are impressive and date to the 8th cent BC.

Amykles, Tempel of Apollo**
11th-3rd cent BC
6 km south of Sparta

Foundations of the Apollo Temple at Amykles, Panoramio

Pausanias was informed that the archaic site of Amyklai had its ancient origin as an Achaean stronghold that predated the "Dorian invasion", and modern archaeology has supported that view. The Bronze Age settlement lay on the slopes above the modern village of Amykles. It was conquered by the Spartans as the fifth of the surrounding settlements whose subjection initiated the history of Sparta, in the eighth century BC; the inhabitants of Amykai took their places among the perioikoi, members of autonomous groups of free but non-citizen inhabitants of Sparta

The Sanctuary of Apollo, enclosing within its temenos the tumulus of Hyakinthos, a pre-Hellene divinity, whose cult was conflated with that of Apollo, in the annual festival of the Hyakinthia. There have been finds of sub-Mycenaean votive figures and of votive figures from the Geometric period, but with a gap in continuity between them. "A radical reinterpretation had taken place" Walter Burkert has observed, instancing many examples of this break in cult during the "Greek Dark Ages", including Amyklai

After the Spartan conquest, Amyklai continued to hold the Gymnopaideia and the Hyakinthia, now celebrated in honor of Apollo Amyklaios, given an even later political interpretation, as celebrating "the political reconciliation of Doric Sparta (Apollo) with the Achaian population of Amyklai (Hyakinthos).

In the seventh or early sixth century, a colossal archaic helmeted effigy was made of bronze, taking the semi-aniconic form of a stout column with arms, holding a spear as well as the more familiar bow: "ancient and made without artistry," judged Pausanias. "Except for the face and the tips of its feet and hands it looks like a bronze pillar. It has a helmet on its head, and a spear and a bow in its hands. The base of the statue is shaped like an altar, and Hyakinthos is said to be buried in it." (Pausanias, III.6). - In the mid-sixth century the face of Apollo had been veneered with gold from Lydia, a gift of Croesus.

Neolithic traces of human habitation and burials

Boat ride on the underground river (Glyphada)

Map of the caves from Planetware

The Diros Caves (Glyphada and Alepotrypa) are located approximately 12 miles south of Areopolis. Glyphada is part of an underground river. About 5,000 meters have been exposed and accessible by small boats and through narrow passageways. One is surrounded by formations of stalagmites and stalactites.

Archaeological research (Dr. George Papathanasopoulos) has shown that Alepotrypa has served as place of worship and burials in Neolithic times. Its inhabitants were farmers.
