The Louvre is raising ticket prices.

The Louvre Museum said it would raise its basic ticket price from 17 to 22 euros from next month in the latest sign that visitors may face higher costs ahead of the Summer Olympics in Paris. The Louvre is expecting to have welcomed nearly 9 million visitors by the end of the year, and is raising its prices by 30 percent to help offset rising energy costs. The increase was not tied to the Paris Summer Olympics, but it was seen as part of a larger trend of rising prices across the French capital as it prepares to host nearly 10 million people in town for the Games. The city's transportation agency was considering doubling the price of a Metro ride to 4 for the duration of the Summer Olympics to cover increased operation costs.
