text: While the overriding atmosphere of the interior and exterior of the palace is of the 18th century, the palace itself is not. Much of its appearance is a result of a long evolution dating from the 12th century, overshadowed by heavy restoration and refurnishing during the 19th and 20th centuries.
  Grimaldi fortress
  Monaco's history predates the Roman occupation of AD 122. Its large natural harbour ensured a steady stream of visitors from Byblos, Tyre, and Sidon. Later the Phoenicians came to trade silk, oil, and spices with the natives. It was the Phoenicians who introduced to this area of the Mediterranean their god Melkart, later known by the Romans as Hercules Monoikos. It was after this god that the Romans renamed the area Portus Hercules Moneici, which has evolved to the present name of Monaco.
  The seat of the Prince of Monaco was established on the Rocher de Monaco (Illustration 5) as a fortress in 1191 when the harbour, that is today lined by Monte Carlo, was acquired by the Republic of Genoa. The harbour and its immediate area were given to the Genoese by the Emperor Henry IV with the proviso that the Genoese protect the coastline from piracy. Further territory was ceded to the new owners by the Council of Peille and the Abbaye de Saint Pons. In 1215 work began on a new fortress, comprising four towers connected by ramparts protected by a curtain wall. This forms the core of the present palace.
