It was here where in 480 B.C the Spartan King Leonidas, with 300 Spartans, 700 Thespians and 80 Mycenaeans, fought against the Persian lead by Xerxes and fell heroically.

Thermopylaes derives its name from several natural hot water springs which still exist close to the foot of the hill.

 A most picturesque village tucked away in the green vegetation of Kallidromo mountain with an incredible view and special cultural importance. Its medieval Castle (13th B.C.) is one of the most important and well preserved castles of its era.

Its well-preserved stonework illustrates the historic continuity from the 5th Century B.C down to World War II. The castle is home to the Archaeological Museum and the XIV Department of Prehistoric and Classical Antiquities.

In 1973, an area of the Castle of Lamia was given to the Ministry of Culture where in 1984 the Municipality of Lamia undertook its repair for the accommodation of the Archaeological Museum. From the most important exhibits of the Museum are: The Golden Mycenae circlet (14th century b.C.), the Helmet from teeth of boar from the vaulted Mycenae Grave of Elatia village (14th century b.C.), the Ostrako–this exhibit constitutes the first depiction of martial boat in the History of Continental Greece (12th century b.C.) and many others.

Stone bridges, waterfalls, the historical bridge, the Memorial of National Resistance, the Monastery of Gorgoipikoou, the monastery of Metamorphosis and the water-mill of Platania are just some of the areas worth visiting surrounded by the exquisite beauty of the mountain.

Delphi, located on Mount Parnassus, next to the Sanctuary of Apollo, is the site of the most important ancient Oracle, Pythia. The foundation of Delphi and its oracle is said to have taken place before the times of recorded history and its origins are obscure, but dating to the worship of the Great Goddess, Gaia. In 1893 archaeologists from the École française d'Athènes finally located the actual site of ancient Delphi.
