Fine dining, ancient buildings, world class galleries and sun-kissed beaches. As a tourist destination, Europe has it all.

Tourism is a vital part of the European Union's economy, generating more than 10 percent of the region's gross domestic product and employing 9.7 million people across 1.8 million businesses, according to the European Commission. And with a weak euro, it's never been a better time to visit the 19 countries that use the single currency.

In this slideshow, CNBC looks at mainland Europe's 10 most popular tourist destinations in 2014 based on the number of nights spent in tourist accommodation over 10 months. The figures come from Eurostat, the European Commission's statistical body.

Nights spent in tourist accommodation: 370 million

Those looking for la dolce vita can't go wrong with a trip to Italy. A cradle of European civilization, the Italian way of life has beguiled travelers – perhaps most notably the English poets Lord Byron, Percy Bysshe Shelley and John Keats – for centuries.

Tourists in the country are spoiled for choice. Culture vultures need look no further than the "eternal city" of Rome, home to the Ancient Roman Coliseum and the Vatican's Sistine Chapel, while Venice is as romantic as it is architecturally stunning. And the world famous pizzas and gelato of Naples—a popular stopping off point for Mediterranean cruise ships—offer travelers a rough-edged slice of Italian life.

Every year, foreign travelers spend over 30 billion euros ($33 billion) in Italy, with tourism providing around one-third of the country's GDP and more than one million jobs, according to Italy's Ministry of Foreign Affairs and International Cooperation.

Nights spent in tourist accommodation: 401 million

The land of tapas, jamón and bullfighting, Spain is an iconic destination for travelers from around the world.

While Madrid's wild nightlife doesn't get going until 11 p.m., travelers looking for a more sedate experience can head north to the deep green hills and mountains of Asturias and Cantabria, while sun worshipers can relax on the playas of Andalusia's Costa del Sol.

Tourism is crucial to the Spanish economy, which was hit hard by the euro zone debt crisis of 2010.

In 2014, Spain's tourism sector grew by 2.9 percent, according to Exceltur, a group that represents the Spanish tourism industry. This rate was twice as fast as Spain's overall GDP growth of 1.4 percent.
