Speaking of which, the Raleigh Palace can be traced back to the period of the ancient Republic of Genoa, including the mansions of many nobles in the history of Genoa, and it was also one of the important places for receiving state visits. The decoration of the palace is extremely luxurious, once using cement mixed with gold plating and so on. In 2006, the Raleigh Palace was listed as a World Heritage Site by UNESCO. This complex includes 42 buildings, the most famous of which is Garibaldi Street, also known as "New Street". The Palazzo Rosso, Palazzo Bianco and Palazzo Tulsi preserve an extraordinary artistic heritage within the "New Street" museum. The entire Palazzo Rosso can be called a museum: its halls are decorated by painters of the Genoese school. Palazzo Bianco is more of an art gallery with paintings by Spanish, Italian and Genoese artists. The Tulsi Palace is the current seat of the City Hall. The Royal Palace and the National Gallery Spinola Palace are also important museums in the city.
