Insider Monkey Score: 14

Not only flamenco dancing, football clubs, mesmerizing food, stunning art, and distinctive folklore, but Spain is also popular for its fascinating heritage sites, particularly its castillos. The ‘Alcázar’ in Segovia is one of the most famous monuments in the Mediterranean country. It was originally a Muslim fortress in the 11th century, later modified and enlarged by Christian kings. 

In 2022, the Spanish Government announced an investment of €35 million ($37.9 million) for the maintenance and rehabilitation of the country’s historical heritage for tourism use.
