The seldom visited country of Albania offers a wealth of historical interest. The important port of DURRES is the second largest city in Albania. Colonised by the Greeks in 627 BC, the city was an important port and trading centre on the trading route between Rome and Byzantium (Istanbul) between the first and third centuries. From the Venetian Tower at the harbour, the medieval Town Wall leads to the Amphitheatre dating back to the second century BC and containing an early Christian crypt with a rare wall mosaic. There is also an excellent Archaeological Museum.
