Chalcedon
The site of Chalcedon is located on a small peninsula on the north coast of the Sea of Marmara, near the mouth of the Bosphorus. A stream, called the Chalcis or Chalcedon in antiquity and now known as the Kurbağalıdere (Turkish: "stream with frogs"), flows into Fenerbahçe bay. There Greek colonists from Megara in Attica founded the settlement of Chalcedon in 685 BC, some seventeen years before Byzantium.
Chaeronea
Chaeronea was the site of several historical battles. Best known is that of 338 BCE, between Philip II of Macedon and a coalition of various Greek states, mainly Thebes and Athens. During the battle, the elite unit of Theban soldiers known as the Sacred Band of Thebes was wiped out completely (See Battle of Chaeronea). In 1818, the so-called Lion of Chaeronea, a nearly funerary monument erected in honor of the Sacred Band, was rediscovered by English travellers. The fragmentary monument was reassembled and installed in 1902 by an organisation called the Order of Chaeronea atop a pedestal at the site of its discovery. The ancient biographer and essayist Plutarch was born in Chaeronea, and several times refers to these and other facts about his native place in his writings.
