The city council has announced stricter controls on the access of private vehicles to Villa Borghese, which is currently celebrating its 100th year as a public park. According to the new rules, cars and motorbikes are not supposed to enter the park without a permit, which will only be made available to drivers under certain circumstances. Permits cost between 9 for a day and 300 for a year. People who live inside Villa Borghese can drive in the park free of charge. The restrictions are valid until October.
