After the independence of 1960 and the civil war of 1974, Cypriot tourism, which had been relatively closed until then, is developing. Due to the favorable weather conditions, good public safety, rich cultural heritage and the large number of English-speaking islanders, tourism started to develop explosively in the 1980s. Due to the forced divisions of the island until the 2000s, only the southern free areas could be officially visited, the northern, occupied territories could not be entered from within the island. From the outside of the island to the so-called Northern Cyprus Republic, the Republic of Cyprus is still regarded as an illegal border crossing. From April 2003, a border crossing was opened on the ceasefire line, which was followed in 2008 by the opening of a new crossing in the center of Nicosia (Ledra Street). Most visitors (nearly half of the tourists) come from Great Britain due to traditionally good relationships. The proportion of tourists coming from major European countries (Germany, Sweden) is significant. The number of visitors to Cyprus is about three million people a year - that is, three times the population of the island. Tourism accounts for about a quarter of the total national product. Tourism is coordinated by the Cyprus Tourism Office (CTO). Hepatitis A (high risk of infection) and B (moderate risk of infection) are recommended for travelers in Cyprus.
