National Park Service rangers had to round up more than a dozen tourists who ignored warnings that St. Augustine monument was closed because of the partial federal shutdown.
The Castillo de San Marcos National Monument is among the national parks and monuments closed amid the ongoing federal budget battle.
On Monday, park rangers said 13 adults and two children ignored warning signs and went inside the fort.
Eric Masurier of Clermont told WFTV that he encouraged the group to follow him inside. He says he didn't understand why he couldn't get inside the monument if he paid federal taxes.
Rangers issued the group verbal warnings.
Castillo de San Marcos is the oldest masonry fort in the continental U.S. It was built when Florida belonged to Spain.
