Tourism in modern-day Greece started to flourish in the 1960s and 1970s, in what became known as mass tourism. During that time, large-scale construction projects for hotels and other such facilities were undertaken, and the country saw an increase in international tourists over the years. International events such as the 2004 Summer Olympic Games and the Eurovision Song Contest 2006, both held in Athens, greatly helped to boost tourism in the country, while large-scale nationally funded cultural infrastructure such as the New Acropolis Museum also contributed to the flow of tourists in the country. Thessaloniki was the European Youth capital in 2014.
