Next time you visit Rome, be prepared to spend more euros than you’re used to.

Tourists who visit the Pantheon, an ancient Roman temple and one of the most famous sites in the Italian capital, may soon need to pay a fee in order to explore the building. The site is currently one of the few free monuments for visitors to see in the city.

The change is planned to take place early next year, according to Italian culture minister Dario Franceschini. The proposed fee has not been decided yet, but Franceschini says it will be “no more than a few euros.”

The new charge was proposed in order to cover the costs to maintain the ancient site. With other 7 million visitors (and growing) each year, the Pantheon's structure is coming under a great deal of stress and wear. Built between 118 and 125 A.D., the site is nearly 2000 years old.

Many other sites in Italy have been struggling to maintain their monuments during times of tourism booms. Both Florence and Venice have been restricting tourists from crowding fragile and historical sites.

Some tiny fees are worth paying if they keep historical sites around for future generations to admire.
